Note:
This unit is equipped with an FM/AM allocation selector on
the rear panel. The specifications shown above are correct
with this selector set to the “FM 0.2 MHz/AM 10 kHz” position.
If it is set to the “FM 0.05 MHz/AM 9 kHz” position, however, the
FM frequency range becomes 87.50~108.00 MHz, and the AM
frequency becomes 522~1611 kHz.
Weights and dimensions shown are approximate.

Note: AM OSC Coil (L202) and AM 2nd IFT (T202) have been already adjusted, and require no adjustment.
[ AM TUNER ADJUSTMENT |
Setting and Equipment used
. ACand DC electronic voltmeters (VT VM)
. AM signal generator (AM-SG)
. Maintain line voltage at 120 volts.
. Output of signal generator should be no higher than
necessary to obtain an output reading.
. Pull the AM ferrite-bar antenna (L201) outward.
. Set input selector to ‘tuner’ position.
Use a non-metal screwdriver for the adjustment.
Set FM-AM muting/mode switch to ‘‘on/FM auto” position.
Set band selector to ‘‘AM”' position.
Set tape monitor switch to ‘source’ position.
Set speaker selector to ‘‘main” position.
Set automatic-scan switch to “off"’ position.
Set FM/AM allocation selector to “‘0.2MHz/10kHz”’ position.

must be 12dB plus (IHF). That is, when input is 60dB, SG
output is to be 72dB.
