IMPORTANT NOTICE
This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.
It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already known and understood by the users,
and have therefore not been restated.
WARNING:
Failure to follow appropriate service and safety procedures when servicing this product may result in personal injury, destruction of expensive
components, and failure of the product to perform as specified. For these reasons, we advise all YAMAHA product owners that any service required
should be performed by an authorized YAMAHA Retailer or the appointed service representative.
IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or recognition of any applicable
technical capabilities, or establish a principle-agent relationship of any form.
The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and service departments of YAMAHA are
continually striving to improve YAMAHA products. Modifications are, therefore, inevitable and specifications are subject to change without notice or obligation to
retrofit. Should any discrepancy appear to exist, please contact the distributor's Service Division.
WARNING:
Static discharges can destroy expensive components. Discharge any static electricity your body may have accumulated by grounding yourself to the
ground buss in the unit (heavy gauge black wires connect to this buss).
IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and
possibly other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.
About lead free solder
All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder.
Among some types of lead free solder currently available, it is recommended to use one of the following types for the repair
work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than that of the lead solder, be sure
to use a soldering iron suitable to each solder.

■ DISASSEMBLY PROCEDURES
(Remove parts in the order as numbered.)
Disconnect the power cable from the AC outlet.
Spread a rubber sheet and cloth, then place the main unit upside down on it.
2. Removal of Driver
a. Remove 4 screws (1)and then remove the driver.
(Fig. 1)
b. Disconnect the connector connected to the terminal of
the driver. (Fig. 1)
1. Removal of Front Grille Ass’y
* The front grille ass’y is fixed to the cabinet with dowels at 5 locations.
As a flatblade screwdriver is used for removal, use
special care not to cause damage to the cabinet
ass’y.
a. Using the flatblade screwdriver inserted in the gap between the front grille ass’y and the cabinet ass’y (bottom side first), push up the front grille ass’y. (Fig. 1)
b. Remove the front grille ass’y by lifting a metalblade up.
(Fig. 1)
* When installing the front grille ass’y, apply quick-drying bond or the like to dowels and then fit them into
dowel holes for secure installation. (The front grille
ass’y will come off easily if its dowels are fitted into
dowel holes without applying quickdrying bond or
the like.)

■ CHECKS AND ADJUSTMENTS
● Confirmation of power amplifier operation
For the power amplifier which has been repaired, it is absolutely necessary to confirm that a correct waveform is obtained
at points indicated by A and B in the schematic diagram according to the following procedure.
Devices required
Signal generator
8-ohm or 6-ohm load resistor
Oscilloscope (dual trace type)
Connection
1) Connect the output signal from the signal generator to the input terminal of the main unit.
2) Disconnect the connector terminal connected to
the speaker unit and reconnect it to the load resistor.
3) Connect the HOT side of the oscilloscope CH1
probe to the point A or B indicated in the figure and
the GND side to the GND of the main unit. (Fig. 1)
4) Connect the oscilloscope CH2 input to the red side
of the connector cable, which is connected with the
load resistor.
At this time, the GND terminal of CH2 must be left
unconnected.
Setting
1) Set the signal generator to the sine wave, 100 Hz
and minimum output level settings.
2) Set the volume of the main unit to the minimum position.
3) Turn on the power to the main unit.
4) Adjust the output level of the signal generator and
the volume of the main unit so that the output level
observed at oscilloscope CH2 is 26 Vp-p to 28 Vp-p.
● Idling adjustment
To stabilize operation of the amplifier, turn ON the power with no input signal and wait for 2 to 3 minutes in non loaded
condition before the adjustment.
Confirm that the voltage across the terminals TP1 and TP2 is 20 mV to 350 mV.
If it exceeds 350 mV, open (cut off) R136.
Attention:
If the idling current exceeds 350 mV after a power amplifier repair, check for a defective component before cutting the
resistor.
MAIN (1) P.C.B.

Waveform observation
With the settings made as described above, observe

● Confirmation of AUTO STANDBY operation setting
1) Turn off the “POWER ON/OFF” key located on the rear panel.
2) In order to shorten the time required for operation check; connect a 10 k-ohms resistor at both ends of R45 on the
MAIN (2) P.C.B.. (Fig. 2)
3) Connect the output signal from the signal generator to the INPUT 2 / L/MONO terminal of the main unit.
4) Set the signal generator for the sine wave of 100 Hz, 8 mV.
5) Turn on the “POWER ON/OFF” key located on the rear panel.
Confirmation
1) Set the “AUTO STANDBY” key to the LOW position.
4) Set the “AUTO STANDBY” key to the HIGH position.
2) Turn on the “STANDBY/ON” key.
The status indicator lights up (green) and its color
changes to red after 2 to 8 seconds.
3) Turn off the “STANDBY/ON” key.
The status indicator goes off.
5) Turn on the “STANDBY/ON” key.
The status indicator lights up (green) and its color
remains unchanged even after time have elapsed.
6) Turn off the “STANDBY/ON” key.
The status indicator goes off.
After confirmation
1) Turn off the “POWER ON/OFF” key.
2) Disconnect the 10 k-ohms resistor connected to both ends of R45.
