Warning: When using electric products, basic precautions should always be followed,
including the following:
Attention: Lors de l’utilisation de produits électrique, assurez-vous d’adhérer à des
précautions de bases incluant celle qui suivent:
Power Sources
Your unit should be connected to a power source only of the voltage specified in the
owners manual or as marked on the unit. This unit has a polarized plug. Do not use
with an extension cord or receptacle unless the plug can be fully inserted. Precautions should be taken so that the grounding scheme on the unit is not defeated. An
apparatus with CLASS I construction shall be connected to a Mains socket outlet with
a protective earthing ground. Where the MAINS plug or an appliance coupler is used
as the disconnect device, the disconnect device shall remain readily operable.
Hazards
Do not place this product on an unstable cart, stand, tripod, bracket or table. The
product may fall, causing serious personal injury and serious damage to the product.
Use only with cart, stand, tripod, bracket, or table recommended by the manufacturer
or sold with the product. Follow the manufacturer’s instructions when installing the
product and use mounting accessories recommended by the manufacturer. Only use
attachments/accessories specified by the manufacturer
Note: Prolonged use of headphones at a high volume may cause
health damage on your ears.
The apparatus should not be exposed to dripping or splashing water; no objects
filled with liquids should be placed on the apparatus.
Terminals marked with the “lightning bolt” are hazardous live; the external wiring
connected to these terminals require installation by an instructed person or the use of
ready made leads or cords.
Ensure that proper ventilation is provided around the appliance. Do not install near
any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
No naked flame sources, such as lighted candles, should be placed on the apparatus.
Power Cord
Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug
has two blades with one wider than the other. A grounding type plug has two blades and a
third grounding prong. The wide blade or the third prong are provided for your safety. If the
provided plug does not fit into your outlet, consult an electrician for replacement of the
obsolete outlet. The AC supply cord should be routed so that it is unlikely that it will be
damaged. Protect the power cord from being walked on or pinched particularly at plugs. If
the AC supply cord is damaged DO NOT OPERATE THE UNIT. To completely disconnect
this apparatus from the AC Mains, disconnect the power supply cord plug from the AC
receptacle. The mains plug of the power supply cord shall remain readily operable.
Unplug this apparatus during lightning storms or when unused for long periods of time.
Service
The unit should be serviced only by qualified service personnel. Servicing is required
when the apparatus has been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate normally, or has been dropped.
Alimentation
L’appareil ne doit être branché qu’à une source d’alimentation correspondant au
voltage spécifié dans le manuel ou tel qu’indiqué sur l’appareil. Cet appareil est équipé
d’une prise d’alimentation polarisée. Ne pas utiliser cet appareil avec un cordon de
raccordement à moins qu’il soit possible d’insérer complètement les trois lames. Des
précautions doivent êtres prises afin d’eviter que le système de mise à la terre de
l’appareil ne soit désengagé. Un appareil construit selon les normes de CLASS I
devrait être raccordé à une prise murale d’alimentation avec connexion intacte de mise
à la masse. Lorsqu’une prise de branchement ou un coupleur d'appareils est utilisée
comme dispositif de débranchement, ce dispositif de débranchement devra demeurer
pleinement fonctionnel avec raccordement à la masse.
Risque
Ne pas placer cet appareil sur un chariot, un support, un trépied ou une table instables.
L’appareil pourrait tomber et blesser quelqu’un ou subir des dommages importants.
Utiliser seulement un chariot, un support, un trépied ou une table recommandés par le
fabricant ou vendus avec le produit. Suivre les instructions du fabricant pour installer
l’appareil et utiliser les accessoires recommandés par le fabricant. Utilisez seulement
les attachements/accessoires indiqués par le fabricant
Note: L'utilisation prolongée des écouteurs à un volume élevé peut
avoir des conséquences néfastes sur la santé sur vos oreilles. .
Il convient de ne pas placer sur l’appareil de sources de flammes nues, telles que
des bougies allumées.
L’appeil ne doit pas être exposé à des égouttements d’eau ou des éclaboussures
et qu’aucun objet rempli de liquide tel que des vases ne doit être placé sur l’appareil.
Assurez que lappareil est fourni de la propre ventilation. Ne procédez pas à
l’installation près de source de chaleur tels que radiateurs, registre de chaleur, fours
ou autres appareils (incluant les amplificateurs) qui produisent de la chaleur.
Les dispositifs marqués d’une symbole “d’éclair” sont des parties dangereuses
au toucher et que les câblages extérieurs connectés à ces dispositifs de
connection extérieure doivent être effectivés par un opérateur formé ou en utilisant
des cordons déjà préparés.
Cordon d’Alimentation
Ne pas enlever le dispositif de sécurité sur la prise polarisée ou la prise avec tige de
mise à la masse du cordon d’alimentation. Une prise polarisée dispose de deux lames
dont une plus large que l’autre. Une prise avec tige de mise à la masse dispose de
deux lames en plus d’une troisième tige qui connecte à la masse. La lame plus large ou
la tige de mise à la masse est prévu pour votre sécurité. La prise murale est désuète si
elle n’est pas conçue pour accepter ce type de prise avec dispositif de sécurité. Dans
ce cas, contactez un électricien pour faire remplacer la prise murale. Évitez
d’endommager le cordon d’alimentation. Protégez le cordon d’alimentation. Assurezvous qu’on ne marche pas dessus et qu’on ne le pince pas en particulier aux prises.
N’UTILISEZ PAS L’APPAREIL si le cordon d’alimentation est endommagé. Pour
débrancher complètement cet appareil de l’alimentation CA principale, déconnectez le
cordon d’alimentation de la prise d’alimentation murale. Le cordon d’alimentation du
bloc d’alimentation de l’appareil doit demeurer pleinement fonctionnel.
Débranchez cet appareil durant les orages ou si inutilisé pendant de longues périodes.
Service
Consultez un technicien qualifié pour l’entretien de votre appareil. L'entretien est
nécessaire quand l'appareil a été endommagé de quelque façon que se soit. Par exemple
si le cordon d’alimentation ou la prise du cordon sont endommagés, si il y a eu du liquide
qui a été renversé à l’intérieur ou des objets sont tombés dans l'appareil, si l'appareil a été
exposé à la pluie ou à l'humidité, si il ne fonctionne pas normalement, ou a été échappé.

Yorkville AP4040 Power Amplifier
M1129 “THE INPUT BOARD”
The input board processes the audio signal from the input jacks to the volume control
board, (M1128).
Each channel consists of a balanced gain stage, switchable subsonic filter, and a
stereo / mono / bridge switch.
Looking at the left channel, the balanced input, (XLR Jack) and unbalanced input
(phone jack) are wired in parallel to the input of a balanced operational amplifier, (U4).
The gain of this stage is 0.82 (-1.3dB) balanced and 1.6 (4.0dB) unbalanced. Resistors
R25, R27 along with capacitors C11 and C12 form a radio interference elimination filter.
Switch S1 selects the cutoff frequency of the hi-pass subsonic filter. The subsonic
filter provides a 20Hz or 40 Hz high pass filter. The filter consists of a tee network on
the input of U3 along with R10, R28, C29 and C30, C33 and C34. The gain is 1 (0dB)
in the passband, (above 100Hz).
The audio signals from the input board M1129 pass through the 14 conductor cable
to board M1128.
M1128 “VOLUME CONTROL BOARD”
This board contains:
• the front panel audio gain controls
• the front panel indicating LED’s (power, protect, activity and clip).
• the audio limiters
Circuit Explanation:
• The left channel of the circuit is explained.
(Refer to the schematic of M1128 as the sections of the circuit are explained.)
The audio signal out of M1129 passes through volume control P2 and the desired
level enters U2 through pin 6. U2 is set for a gain of 5 (14dB) when the volume control
is in the fully clockwise position.
The AP4040’s defeatable limiter is built around LD8. LD8 is an opto-resistive cell
comprising of an LED that shines on a photocell. As the LED in the LD8 becomes
brighter, the resistance of the photocell decreases, placing more of the audio signal on
pin 5 (non-inverting input) of U2. This audio voltage gets subtracted from the signal on
the inverting input and less signal appears on the output of U2. Transistors Q5 and Q6
along with the surrounding passive parts provide the attack and release time constants
of the limiting function along with the drive currents for the clip LED and the LED
inside LD8. When an audio signal on the output of the power amplifier section (on
board M1146) enters clipping, pulses representing the duration of the clipped portion
appear at LCLIP. These pulses turn on transistor Q6, and Q6 provides current pulses
to turn on clip LED LD6. The pulses also pass through R7 and D6 to charge C3 and
C36. When the voltage across C3 reaches 0.5 volts then Q5 turns on providing a current into the LED of the LD8 limiting the audio signal at U2. The charging (attack) and
discharging (release) times of the limiter are 80mS and 3.5 seconds respectively.
Resistors R50 and R7 provide the charging path, and resistor R51 provides the discharge path. The limiter can be defeated by placing the limiter switch (S2) in the in
position which disconnects Q5 and the charging / discharging circuitry from V+.

SERVICE MANUAL
The activity LED circuit consists of Q1 and the surrounding circuitry. The audio signal enters the activity LED circuit through R2. R2 and C21 form a differentiator that
turns Q1 on illuminating the activity LED whenever the audio signal increases in amplitude. A constant current flows through R55A, R55B and when Q1 is off, the collector
current then flows through D1.
From M1128 the audio signal passes through a 12-conductor ribbon cable to circuit
board M1147.
On M1127 an operational amplifier U201 re-references the ground for the audio signal from LREF or RREF to the corresponding LOG (left output ground) or ROG (right
output ground). U201 also provides DC correction for DC offsets appearing on the output binding posts. Feedback from the output binding posts appears on LFNB or RFNB.
Through R203A or R203B the DC offset achieves a gain of -1 from U201. The DC offset of opposite polarity on the output of U201 will compensate for the DC offset in the
amplifier section on M1146 resulting in 0 volts DC on the output binding posts.
• The audio signal continues to M1146 via an 8-conductor ribbon cable.
M1126 “THE VOLTAGE AMPLIFIER AND
CURRENT AMPLIFIER”
This board contains:
• a voltage amplifier section
• a current amplifier section
• amplifier current limit section
• DC output protection
• heatsink temperature sensing
Voltage Amplifier Section
The voltage amplifier amplifies the audio signal’s voltage from 6.8 volts peak (at the
output of U201) to approximately 98v peak, which is required to drive the current
amplifier section. The current amplifier provides the current required for the 98v peak
signal to drive 1200 watts into 4 ohms out of the binding posts.
Before the circuit is described in detail here is a quick rundown on the signal’s path
through the voltage amplifier stage. Refer to the schematic of M1146. Let’s consider
that a positive going AC signal is present at the SIG input. The positive going signal
will turn on the positive side of the voltage amplifier. The signal at the SIG input turns
on Q12A (through R40A, D14A and D13A). The collector of Q12A pulls down on the
base of Q14A turns this transistor on further and allows a greater current to flow out of
Q14A’s collector. This increase in current passes through Q15A and it’s collector to
emitter voltage decreases. The collector of Q15A now being more positive in voltage
turns the base of Q18A on causing an increase in Q18A’s collector current resulting in
test point 1 going positive.
As the positive side of the amplifier was turning on the negative side would have
been turning off. This is how test point 1 was able to move positive following the input
signal. The reverse would hold true if a negative going signal were present on the input
of the voltage amplifier.

SERVICE MANUAL
CIRCUIT DESCRIPTION:
The voltage amplifier is a mirrored image with circuitry connected to the positive power
supply rail being identical (but opposite polarity) to the circuitry connected to the negative power supply rail.
For this reason we will look in detail at the positive side of the amplifier.
The audio signal enters the voltage amplifier at the SIG input. The signal passes
through R40A, D14A and D13A to the base of Q12A. Diodes D13A and D14A set up
the DC bias on Q12A to approximately 0.6 mA.
The first voltage gain stage consists of Q12A along with the resistor chain on its collector and the emitter resistor (R44A).
Transistor Q12A drives the base of Q14A through the resistor chain. A DC current of
approximately 4 mA should flow through the collector of Q14A. The voltage drop
across Q14A remains constant and is derived from the voltage drop across the voltage
reference Q20A, resistor R58A, and the base/emitter junction of Q15A. This total voltage should equal approximately 3 VDC. Transistor Q14A is the second gain stage and
its output current flows through Q15A. Transistor Q15A is a common base stage with
the collector driving the base of output buffer Q18A.
Diode D17A is a clamping diode that prevents the maximum peak of the audio signal from coming within 4V of the 144 VDC rail. This is to prevent the output current
amplifier from going into saturation during clipping and therefore having storage delay
problems.
Transistor Q18A buffers the high impedance present on the collector of Q15A. The
output of the buffer provides a low output impedance at the junction of R61A and
R62A and is current limited to 30mA through the clamping action of D19A, D20A and
D23A. The signal at the junction of R61A and R62A drives the succeeding current
amplifier.
Current Amplifier Section
The current amplifier receives a high voltage audio signal from the voltage amplifier
and provides the current drive necessary to drive speaker cabinets.
The current amplifier is a two-tier complimentary output driver design controlled by a
complimentary darlington stage.
[CIRCUIT DESCRIPTION - REFER TO THE SIMPLIFIED SCHEMATIC #1 ON THE
FOLLOWING PAGE]
QUIESCENT CONDITION:
This design is class A/B and therefore the output driver transistors must be forward
biased to provide low crossover distortion. In most class A/B designs, a diode chain or
VBE multiplier is used to control the bias voltage and provide a means of adjusting the
bias. This design is different, as there isn’t a diode chain or VBE multiplier. For simplicity lets consider only the positive side of the current amplifier, that is all parts between
the positive power supply rails and the audio signal output/input terminals. The negative side is the same as the positive, except for polarity changes.
To bias Q14, greater than 0.5V is needed from base to emitter, (or for simplicity from
base to amplifier output). Points A and B are at the same potential, so consider them
to be connected. If this is true then 0.5V from test point 2 to the amplifier output must
appear across R12. There must be some way of developing this voltage across R12,
and there is using the darington (Q5 and Q40) driver along with local feedback.
Simplified schematic #1 shows the biasing circuit. The current needed to develop 0.5V
across R12 comes from the emitter of Q5. When the amplifier is first turned on the current
source (Q3) turns on Q5 and Q40) and current flows through R12 developing a voltage.
When this voltage approaches 0.5V Q1 turns on and robs current from the base of Q40.

This causes Q40 to turn off until the reduced current flowing through Q5 maintains
0.5V across R12. Q1 will turn off slightly causing Q5 and Q40 to increase their collector
currents. The circuit reaches a point of equilibrium with approximately 0.5V across R12.
Because all output devices are not identical and base emitter voltages vary, some
adjustment must be available to slightly adjust the 0.5V across R12. This is accomplished with RT1. RT1 causes Q1 to turn on slightly more or less resulting in Q5 and
Q40 turning on slightly more or less and therefore R12’ s voltage will be slightly more
or less than 0.5v. The proper quiescent current voltage is 4mV (to be measured
between test points 8 and 9).
The Second Tier and Tier Switching
Refer to the simplified schematic Fig. #1 while reading the following text. One way of
making an amplifier more efficient is to vary the Power Supply Voltage on the collectors of the output transistors (Q14 & Q22). The lower the voltage from collector to emitter, the lower the device dissipation. During quiescent conditions, there is 55VDC on
the collectors of output transistors Q14 and Q22. The peak AC voltage that can appear
on the amplifier’s output is approximately 139V peak. How can an output transistor
deliver a 139V peak when its collector is only at 78VDC? It can if its collector is pulled
up to 144VDC as the output signal’s peak rises above 78VDC. Refer to Fig. #2. The
second tier voltage must remain above the amplifier’s output voltage by amount Vm.
Therefore the circuitry controlling the second tier voltage must increase the tier voltage
before the amplifier’s output voltage reaches 78VDC. This leading voltage is necessary
to compensate for time lag of the second tier circuit during fast rising amplifier output
signals.
The voltage between the amplifier’s output
and test point 4 is approximately 12VDC
derived from the voltage drop across ZD4. We
call this voltage the “floating battery” because it
floats on top of the output audio signal with test
point 4 always being 12VDC greater than the
peak of the output signal. Test point 4 drives the
gate of mos-fet Q11. Q11 controls the transistors of the upper tier. As Q11 turns on its source
forward biases the base of Q13 and Q13 pulls
the collector of Q14 towards the 100 volt rail.
The gate to source voltage needed to turn on
Q11 is approximately 3.5 volts. When the peak
output signal is about 69.5vp (78v-(12v-3.5v))
then Q11 will start to turn on the second tier.
The second tier voltage will remain about 13
volts (Vm) above the peak of the output signal
to the point of clipping where this voltage is reduced to about 6 volts (measured driving an 8 ohm load). Zener ZD8 protects the gate source junction of Q11 and also provides a supply current path through R29 for the “floating battery”.

amount of time was spent on the current limit circuitry so that it may simulate the safe
operating area of the output transistors (SOAR curve). No matter how reactive the load
may be the phase shift that it presents, along with it’s resistive component is used to
set the output current limit of the output transistor stage.
Refer to the schematic of board M1146 while reading the following text. The current
limit circuitry is a mirrored image with circuitry connected to the positive power supply
rail being identical (but opposite polarity) to the circuitry connected to the negative
power supply rail. For this reason we will look at the positive side of the circuitry.
Transistor Q9 measures the peak current flowing through resistor R53. The voltage
across R53 (as a result of the current flowing through it) is scaled down by R55, R35,
R35A, R36, R37, D7 and D11 these parts make up the safe operating area along with
the time constants of C30, R34, C12 and R26. Fig. #3 shows a waveform of the current
that passes through R52 and R53 when the output of the amplifier is shorted to ground.
This can only be seen by using an oscilloscope to measure differentially across R52
and R53. The conditions of the measurement are contained on the diagram. During current limit when Q9 turns on it reduces the voltage across R42. R42 is in series with a
16 volt zener (ZD7) and is also in parallel with the junction of Q8. The current that flows
through R20, ZD7, R42, and R22 normally saturates Q8. When Q9 reduces the voltage
across ZD9 and R42 to below 16.6 volts, Q8 turns off allowing a charge to build up on
C8 through resistors R24 and R25. If current limiting occurs for a long enough duration
to allow C8 to charge to 1.2 volts then Q7 will turn on tripping the relay circuit on board
M1147. As soon as the relay is tripped the audio signal will be turned off at the output
of the voltage amplifiers and will remain off for about 5 seconds before the relay turns
on and allows the audio signal to pass through the amplifier. If a current limit condition
is still present then the whole cycle will occur again and repeat until the load conditions
on the amplifier’s output are safe for the amplifier. When a safe load appears the amplifier will automatically reset and drive that load (the speaker cabinet).
DC Protection
If a DC voltage greater than 8 volts appears on the output of the amplifier for more
than 200 milliseconds then triac Q30 will turn on holding the output at ground potential. MBS4992 is a device that turns on at either + or - 8 volts DC.
NOTE: The Power supply voltages given are those when the amplifier is not driving a
speaker load. This will allow yo to check the tier switching with the cover of the amplifier off and the amplifier, therefore, running cool.
Current Limit Protection Circuitry
To have an amplifier drive 3000 watts into practically any combination of speaker cabinets and know what is a safe load and what is not is a very difficult task. An extensive

NOTE: Every time you replace blown output transistors on a
M1146 board test the DC protection triac with the following circuit.
Conditions of test:
A) Pass a 100Hz 25v peak signal through the M1126 board under test with no load
connected to the amplifier output.
B) Connect points 1 and 2 as shown in the diagram. The amplifier should go into protect mode as the triac (if working) shorted the output of the amplifier to ground, and
the amplifier goes into current limit.
C) Disconnect the triac test circuit and allow the amplifier to complete it’s protect cycle.
D) Reverse connections 1 to 2 and 2 to 1 and test again. The same results as in B)
should be observed if the triac is working.
Only test the triac for one protect cycle as
prolonged testing will heat the triac to a high temperature.

SERVICE MANUAL
If prolonged current limiting occurs on the amplifier’s output transistors then D204 or
D205 (depending on which channel is current limiting) will be forward biased turning on
Q202 (from its off state). Now +144VDC appears on the collector of Q202 and through
R210 and R211 turn on Q203 therefore turning off Q201 by shorting its base emitter
junction. Q201 turning off will turn the relay off and the normally closed contacts (off
state) will short the outputs of the voltage amplifiers to ground so as not to continuously
stress the amplifier’s output transistors. A cycle now occurs. With the voltage amplifiers
now disabled there is no signal driving the output transistors (Q13 to Q28).
The current limit circuit protecting the output transistors (Q13 to Q28) turns off and
D204 and/or D205 are not forward biased and Q202 turns off. Through Q203 and
Q201 the relay is turned back on and the voltage amplifiers are now active again, driving the output transistors. If current limiting still occurs, then the same cycle will occur.
If the cause of current limiting (low impedance or short on the speaker output terminals) has been removed, then the amplifier will continue to operate normally.
The third operation that the relay provides is “overheat shutdown”. If for some reason the fan cannot keep the heatsinks in a safe operating temperature area then the
fan control circuit (on board M1147) will deliver through D207 a positive current to turn
Q203 on and turn Q201 off to turn off the relay and disable the voltage amplifiers.
When the fan has cooled down the temperature of the amplifier, then the signal
through D207 will disappear and the relay circuit will turn on the relay to resume normal operation. Anytime the relay is in the “protect” mode (due to the abnormal states)
then contact pin 4 of the relay will illuminate LD3 (the protect LED on the front panel).
Soft Turn On Circuit
To reduce the “inrush” current that flows through the line cord from the 120 VAC power
source (typical with large linear power supplies), a circuit provides a soft turn on function. When the power switch is turned on, the current that initially flows through the primary of the transformer must flow through SG201 and SG202. These are surgestors
that reduce the peak inrush current flow. After about 500 milliseconds a relay’s contacts short across the surgestors so that they are not stressed by the current flowing
through them under normal operation. A circuit consisting of Q240, Q241, C215, and
the associated resistors provides the time delay for the turn on cycle of the relay. The
circuit is very similar to the shutdown time delay circuit. Refer to the section on the
shutdown circuit for a circuit description.
M1147 SHUTDOWN CIRCUIT, FAN CONTROL CIRCUIT,
and SOFT TURN ON CIRCUIT:

• The shutdown relay and its associated drive circuitry have two possible
operating states.
• Amplifier on under normal operating conditions.
• Amplifier power switch has just been turned OFF/ON, or the amplifier is in current
limit protecting the amplifier’s output transistors, or the amplifier has overheated.
Shutdown Circuit
Here is how the circuit accomplishes these functions. The relay’s normally closed contacts short the output of the voltage amplifiers to ground when the power switch is off.
When the power switch is turned on, the relay remains off (normally closed) for about
6 seconds. C203 charges to 35V and results in Q203 turning off allowing Q201 to turn
on. As Q201 turns on, it connects the negative terminal of the relay’s coil (Pin 16) to
ground energizing the relay and opening the normally closed contacts.
Fan Circuit
Looking at the schematic to board M1147, here is a
quick explanation of the fan control circuit. There is
a temperature sensor (AS35) on each M1146
board. When the amplifier is first turned on, Q207
and Q208 are off. The AS35 temperature sensors
are configured as temperature controlled current
sources. As either temperature sensor begins to
heat up, more current flows through D212 or D218
increasing the voltage drop across R235 or R236.
The hotter temperature sensor will provide more
current than the cooler sensor and therefore develop a higher voltage across it’s associated 8K2
resistor. The higher voltage will forward bias D212
or D218 reverse biasing the cooler temperature
sensor’s diode so that the hotter sensor will control the fan speed. At 40 degrees C there

is 10 volts across R235 or R236 which is enough to turn on Q210, Q208, and Q207 providing 7 DC volts to the fan. Further heating the temperature sensors results in a larger
DC voltage across the fan. To lower the dissipation of Q207, D215, D216, ZD205, ZD206
and R226 turn off Q207 and Q208 when the full wave rectified voltage present of the collector of Q207 reaches approximately 58V by robbing current from the base of Q208.
The maximum fan voltage is 20.5 VDC. ZD207 and R228, R229 and R230 provide a current limiting function. Figure #4 shows the current through these resistors when there is
12VDC across the fan.
Thermal Shutdown Circuit
The emitter of Q210 in the fan circuit is the measuring point for the shutdown voltage.
As the temperature sensing devices (AS35) that control the fan circuit heat up the voltage on the emitter of Q210 rises until at 85 degrees Celsius on the M1146 heatsinks.
The voltage on the emitter of Q210 reaches 18 (85 degrees C) VDC and the amplifier
must be shutdown to protect the output power transistors. ZD202 and D207 become
forward biased and Q203 turns on turning the relay off and muting the audio signal.
After the amplifier cools down the voltage will decrease until Q37 turns off turning the
relay back on enabling the amplifier.
Identifying Defective Boards in the AP4040
STEP 1: VISUAL INSPECTION OF FRONT PANEL AND FAN
• Check to see whether the green power LED is lit. If not, the amplifier has a
power supply (M1147 board), transformer, A.C. switch or line cord problem.
• If the red protect LED stays on or samples off and on, this usually indicates a
problem with the voltage amplifier or current amplifier sections on one or both of
the M1126 boards. Check for misaligned pin connections or see if the ribbon
cables have been cut or pinched through their insulation.
• If the fan is running at full speed at power up this usually indicates a problem
with the fan circuitry on the M1147 board, but it can also be caused by M1146 circuit problems. A damaged AS35 temperature sensor located under the M1146
heatsinks can cause erratic fan behavior.
• No output on either or both channels could be caused by intermittent push
switches on the input board.
STEP 2: VISUAL INSPECTION OF INTERNAL CHASSIS AND INITIAL TESTING
After removing the lid, look for any signs of smoke, charring or burnt components.
Before powering up replace the burnt components, and check the associated circuitry
for damaged parts. Disconnect one M1127 board and test one board at a time to
reduce the possibility of further damage. Use a variac to slowly increase the 120 VAC
up from 0 volts while monitoring the quiescent current with a meter and the speaker
output with an oscilloscope. Watch the speaker output for large DC offsets, or oscillation. Watch the meter for large collector currents flowing. Remember under quiescent
conditions, there should only be 3 to 5 millivolts across test points 8 and 9 on the output stage of the amplifier.

Quick Fix for M1146 & M1126
To speed up the servicing of the AP4020 or AP4040 on your bench, Yorkville
Sound’s service department has developed a method to replace the components most likely to fail when a M1146 amplifier board requires service.
This Quick Fix kit contains the procedure, assembly drawings, and components to perform the Quick Fix to a M1146 or M1126 board.
It should be understood that the person using this procedure knows how to
test resistors, diodes, and transistors to determine if they are defective. This procedure is not intended to be a substitute for one’s lack of electronic capability.
Before starting, look at the board for repair and locate the version number.
It is very important that you follow the procedure for the appropriate circuit
board version number.
A complimentary service manual for the AP4020 power amplifier is supplied with this M1146KIT.
STEP 1. Locate the assembly drawing for the version number printed
on the M1146 or M1126 circuit board to be serviced.
STEP 2. Remove all of the transistors coloured RED on the assembly drawing.
STEP 3. Measure and remove any of the diodes coloured BLUE on the
assembly drawing that may be damaged. Replace a 1N4732A 1W
4V7 zener (#6459) ZD12 along with a series 0.5 ohm R85 resistor.
STEP 4. Rotate the trim pot RT1 fully counter - clockwise as in figure 1.
Inspect and replace any resistors that look burnt. Measure all of
the resistor values coloured YELLOW on the assembly drawing.
The value that you measure may not be exactly what is shown
on the assembly drawing but if the resistor doesn’t look damaged it should measure within + or – 5% of the printed value.

STEP 7. Measure the resistors coloured ORANGE. Since the value of
these resistors is 0.1 ohm, your ohmmeter will measure the
higher series resistance of the test leads if the resistor is OK. If
the resistor is damaged your ohmmeter will read a very high
resistance (an open circuit). Replace any damaged resistors.
STEP 8. Measure the output TO–3 transistors (Q13 to Q28) to determine if any are damaged. Mark any damaged transistors with
a marking pen.
STEP 9. Replace any output transistors that you have marked as being
damaged. Replace any diodes that you have found to be damaged. Replace all of the red transistors that were removed.
STEP 10. Inspect the traces on the circuit board for any that have ‘fused’
open or looklike they got very hot. Bridge and solder a piece of
wire over any damaged traces.
AFTER YOU HAVE REPLACED ALL OF THE NECESSARY COMPONENTS INSPECT
THE REPAIRED BOARD FOR ANY MISSING PARTS, CORRECT VALUES IN THE CORRECT POSITION AND THAT ALL COMPONENTS ARE SOLDERED.
Testing Repaired Circuit Boards
Now that you have rebuilt the M1146 or M1126 circuit board. It is just as
important to properly power up the board. If the sinewave doesn’t look right
check the signal at test point (1) to ensure that the voltage amplifier isn’t distorting the signal. If there is still a damaged part on the board instantly turning it on could blow up the board and you would be back where you started.
Connect the power wires and ground to the power supply. Connect a digital multimeter to test pins 8 and 9 to measure the bias quiescent current
and place a scope probe on the speaker output. Be sure to turn the quiescent current trimpot RT1 fully counter clockwise.
Now using a variac slowly turn up the AC main voltage while monitoring
the quiescent voltage and the speaker output trace on the scope. Watching
these two test points is a good indicator of the health of the board. If you
have a second multimeter connect it up from the speaker output to test
point 4 or 5. As you variac up also check these DC battery voltages to
ensure that they both increase in voltage to approximately +12 or –12 vdc.
If the board looks OK after variacing up to 120vac then slowly turn up the
bias (RT1 trimpot) to obtain 3 to 5 millivolts of bias voltage on test points 8
and 9. Check the speaker output with a 1KHZ sinewave with no load. If this
looks good place the minimum rated load (4 Ohm for M1126, 2 Ohm for
M1146) on the speaker output and increase the sinewave amplitude to the
point of clipping. If the signal looks free of oscillation, place a short across
the speaker posts. The amplifier should go into protect mode after 1/10 of a
second. Remove the short and the sinewave will appear 6 seconds later.
Reassemble the complete amplifier and run just clipping music or pink
noise into the minimum rated speaker load for that model of amplifier. Let
the amplifier heat up for 20 minutes. This will check the thermal mounting of
the transistors and for any weak parts not caught during troubleshooting.
If the amplifier passes this test the product is ready to
return to the customer.
