When this switch issetto the ON position, power issupplied
to the tuner's main circuits. The unit's power switch is
gearedto selectingthe transformer's secondary and so even
at the STAND-BY position,
the unit's circuitry
will work as
long as the power cord is connected to the power outlet.
Disconnect the power cord from the AC power outlet when
the unit is not in regular
use.

FMTuner
The FM front end is comprized of a J-FET
(2SK168) single-stageRF amplifier, and NPN
transistor mixer, and an NPN transistor modified
Clapplocal oscillator.
The IF stageconsists of.
2 dual-element ceramic
filters, a single transistor amplifier element, and
IF systemIC (PA3001-A) which incorporatesthe
IF limiter amplifier, FM detector, ffid the FM
muting circuit.
FM Multiplex Stereo
Decoder
The stereo decoder stageemploys an FM MPX
IC (HA1L56W-P), while the subcarrier signals
(frequencies above 19kHz) are removed by an
- 18dB/oct. active filter consisting of a PNP tran-
sistor. This active filter also serves
asan amplifier
for frequencieswithin its passband,
and eliminates
crosstalk.
AM Tuner
The AM tuner is two wave-bandtuner $rith LW
(150kHz-350kHz) and MW (525kHz-1605kH2).
This employs a 2-ganged
tuning capacitor, a single
element ceramic filter, and an IC (HA1138)
consisting of an RF amplifier, mixer, 2-stageIF
amplifier, detector and AGC circuit.

11. DIAL CORD STRINGING
1.Remove the top cover.
2. Remove the tuning drum from the shaft of the
tuning capacitor.
3. Tie one end of the cord to the stud A located
insidethe tuning drum.
4. Rotate the tuning capacitor right around until
the rotor bladesarefully intermeshed.
5. Secure the tuning drum back onto the tuning
capacitor shaft, making sure that the securing
screwfaces
directly upward.
6. Pass
the cord out through the small opening in
the circumference of the tuning drum (see
diagram), and then take it over pulleys B and
C in that sequence.
7.Wind the cord around the tuning shaft 3 times.
8. Pass
it overpulley D, wind it around the tuning
drum 2 times, and finally tie it to the spring
hook F sothat it istensioned.

9. Turn the tuning shaft, and checkthat the cord
moves
smoothly.
10. Cut off any excesscord.
11. Turn the tuning shaft counter-clockwise
asfar
as
it will go.
12. Align the dial pointer with the starting point
of the dial scale,and then pass
the cord over it.
13. Check that the dial pointer is in line with the
starting point of the dial scale.
14. Finally apply the locking paint to the cord
securing positions (stud A and spring hook F)
and the dial pointer connection.

o Check that the dial pointer indicates a starting point.
o Connect the SIGNAL meter between terminal no. 5 of tuner ass'y and the ground.
o connect the TUNING meter between terminals no. 1 and no. 2 of tuner ass'y.
o Set the FM switch to ON and the FM MUTING switch to OFF.
NOTE:
Connect the MPX SG to the FM SG external modulator terminal and set the modulation to Main (IhHz, L+R) +67.5hH2
