CIRCUIT DESCRIPTION
It incorporates an
independent differential
of the equalizer
circuit in the first stage
amplifier whose DC supply uses twin plus
and minus.
SIGNAL PATH
1. The FM broadcast signal waveform from the
antenna is fed to the two dual- gate
MOS
field-effect transistors in the front end for
radio frequency amplification. This signal is
converted into an intermediate frequency by
the dual- gate MOS FET mixer stage in combination with the
signal from the local oscil-
lator.
2. The intermediate frequency signal ,
con-
verted within the front end ,
is fed to four
ceramic filters and three ICs , where it is
tuned , amplified , and detected , becoming a
audio frequency (composite) signal.
The composite signal following detection is
fed to the 4 CH MPX terminal jack and the
multiplex decoder stage.
3. The multiplex decoder stage uses one IC for
three functions: to demodulate the composite signal into the left and right
stereo signals ,
channel
to operate the automatic
mode switching between stereo/mono , and
to switch the stereo indicator lamp appropriately.
The decoding
system uses a phase locked
loop (PLL) circuit , which assures continuous
stable operation and excellent stereo sepa-
ration with low susceptibility
noise (such as car ignition
to external
noise) and
ambient temperature changes.
After decoding, the signal is fed to four
transistors and one LC filter ,
where the
residual carrier component (38kHz , 19kHz
and SCA) is rejected , and then to the audio
amplifier section.
4. The FM muting circuit consists effectively of
two circuits , designed to reduce the pulse
noise which can so easily
arise
when a
muting circuit is operative.
The one circuit is an electronic switch incorporated into the IC , so that the de-
modulated circuit is switched off and on in
the IC , and the other short- circuits the audio
signal by means of a reed relay.
5. The AM tuner section employs
one mono-
lithic IC which functions as radio frequency
amplifier , frequency converter , local oscillator , intermediate frequency amplifier , and
detector. The output is a pure audio signal.
6. The signals which are applied to the MIC and
PHONO terminal jacks are selected by the
FUNCTION switch before being fed to the
first stage of the three- stage differential
direct- coupled equalizer amplifier by which
the signals are amplified.
In order to reduce the switch noise , the
circuit configuration employed enables the
potential at the input and output terminals
to be set at near zero volts.
7. The output from the equalizer amplifier
together with that from the AUX terminal
jacks , the audio signal from the AM tuner
and the audio signal from the FM tuner , are
all selected by the FUNCTION switch , and
pass through the switch circuits for TAPE
DUPLICATE , TAPE MONITOR , 4 CH
ADAPTOR DOLBY NR ADAPTOR , and
the circuits for BALANCE and VOLUME
controls , before being fed to the control
amplifier.
8. The control amplifier has an extremely high
input impedance ,
sistors in a
using PNP and NPN trandirect-coupled two- stage circuit.
This greatly reduces the influence of the
performance inherent in equipment connected externally.
The output from this
two- stage
direct-
coupled circuit is divided into two circuit
systems.
One goes to the
TONE switch via the twin
tone control circuit ,
and the other goes
directly and unmodified in any way .to the
TONE switch. The TONE switch selects
between them.
9. The amplifier section of the twin control has
closed loop NFB amplifiers
for both the
main and sub circuits , each of which has its
own transistor , eliminating mutual interference.
10. The control amplifier output is fed to the
power amplifier after passing through the
LOW FILTER , HIGH FILTER and AUDIO
MUTING circuits.
The first stage of the power amplifier is a
differential amplifier element with constant
current load , and the second stage , too , uses
a differential amplifier element , so that DC
potential drift is prevented.
On the other hand , the final output stage
uses two power transistors in parallel in both
the upper and lower circuits , so that large
collector dissipation is possible.
Again , in order to reduce the distortion
which occurs at low signal levels , the idle
current has been set at a standard level of
100mA.
11. The power amplifier output is fed to the
three push buttons which form the
SPEAKER switch. This selects A , B , and C
speaker system terminal connection.
If all
three speaker systems were to
the effective
connected simultaneously,
speaker impedance might be less than 4il.
To guard against this possibility, when all
three buttons are depressed together , all
three systems are disconnected from the
amplifier.
12. The power amplifier circuit board includes a
power limiter circuit which is independent
circuit. If the power transistor
of the signal
current exceeds the maximum rated value
the power limiter circuit shorts
the input
signal to protect the power transistors.
The ' sensing ' for this protective circuit is
performed by detecting the voltage drop
across the emitter resistors of the power
transistors. There are also protective circuit
which guard against DC potentials at the
power amplifier output junctions , against
speaker complex load impedances less than
, and shorts across the speaker terminals.
Their operation is such that , under the corresponding abnormal condition , a relay acts
to separate
the output junction and the
Further , these protective
output circuit.
circuits also help to mute
DIAL CORD STRINGING
1. Turn the tuning capacitor so that its plates
protrude as much as possible.
2. Tie one end of the string to the spring on the
TUNING pulley (attached to the
tuning
capacitor ).
3. Lead the string around pulley A , then wind
it three turns around the TUNING shaft.
4. Lead the string around pulleys B , C and D
then wind it 1- 1/2 turns around the TUNING pulley.
5. Now tie the other end of the string to the
spring on the TUNING pulley. Turn the
TUNING shaft and check for proper function. Then trim the ends of the string.
6. Turn the TUNING shaft until the plates of
the variable are all the way in. Move the
pointer to the left-end starting point on the
dial and fasten
the unwanted
signal which immediately follows switching
the POWER switch ON , and to immediately
disconnect the output after switched OFF.

Control Settings
Set the controls (knob and switches) of the SX- 1010 as follows:
POWER:
FUNCTION: FM
FM MUTING: OFF
2. Connections between Test Equipment and the SX- 1010
. The output from an FM signal generator should be connected to the 300Q antenna terminals
of the SX- 1010.
. A distortion meter should be connected to the TAPE REC terminal jacks on the SX- I010.
. An AC millivolt meter should be connected to the TAPE REC terminal jacks on the SX- 1010
in parallel with the distortion meter.
kHz.
3. Set both the FM signal generator and the SX- 1010 to indicate 98MHz.
4. Turn the FM signal generator output level down to minimum.
5. Turn the lower core and adjust so that the TUNING meter needle is centered.---r
6. Increase the FM signal generator output to 60dB , modulated at 400Hz , with a deviation of :1:75
7. Turn the upper core and adjust so that the distortion is at a minimum.
Steps 4 ~ 7 above should be repeated several times in succession , until no significant improvement is obtained.

ALIGNING THE FM MPX SECTION
Note: This set of adjustments should not be carried out until the alignment of the FM section
(1 ~ 12 above) has been completed.
The multiplex signal generator should be connected to the external modulator terminals
of the FM signal generator.

Control Settings
Set the controls (knob and switches) of the SX- 1010 as follows:
POWER:

2. Connections between the Test Equipment and the SX- 1010
. The output
from the FM signal generator should be connected to the 300,Q antenna
terminals of the SX- 1010.
. The
oscilloscope X plates (horizontal inputs) should be connected to the PILOT OUT
terminals on the MPX signal generator , and the Y plates (vertical inputs) to terminal number
24.
millivolt meter should be connected to the TAPE REC terminals (with changeover
possible from L to R channels).

ALIGNING THE POWER AMPLIFIER SECTION
Note: There
are individual circuit boards for the Rand L channels. The following instructions
apply to both channels (boards) and should be carried out for each in turn.
1. Nothing should be connected to the input jacks of the SX- 101O , and an 8.\1 dummy resistor
should be connected across the speaker terminals.
2. A DC millivolt meter should be connected across between terminal number 19 and earth.
3. Adjustment should be made to bring the voltage to zero.
4. The DC voltmeter should be connected between terminals number 14 and 16.
5. Adjustment should be made to bring the voltage to 50m
