Set the signal generator to 1650KHz. Place the tuning pointer in the high frequency end and
adjust the oscillator trimmer
on the oscillator tuning capacitor (CA-2) for maximum
audio
output.
Repeat the step 1 and 2 until no further adjustment is necessary.
Set the generator to GOOKHz and tune the receiver to the same frequency and adjust a slug
core of AM ferrite rod antenna for maximum output.
Set the generator to 1400KHz and tune the receiver to the same frequency and adjust the
trimming capacitors of antenna (CA-1) for maximum output.
Repeat the step 4 and 5 until no further adjustment is necessary.
Note:
During tracking alignment reduce the signal generator output as necessary to avoid AGC
action.

a
~
Connect an FM signal generator to the FM ANTENNA
terminals and a oscilloscope and an
audio distortion analyzer to the TAPE MONITOR OUT jacks on the rear panel.
Set the FM SG to 108.5MHz and provide about 3 to 5uV output. Rotate the tuning knob and
place the tuning pointer at the high frequency end and adjust the trimming capacitor C187
for maximum output.
Repeat the step 2 and 3 until no further adjustment is necessary.
Set the FM SG to 90MHz and tune the receiver to the same frequency. Decrease signal
generator output until the audio output level decreases with the decreasing generator output.
Adjust the antenna
coil L101, RF coil L102 and IF transformer L105 for minimum
audio
distortion.
Repeat the step 5 and 6 until no further adjustment is necessary.
