I bought the service-manual of the sony ICB-1020(an old transmitter-receiver) at "www.Owners-Manual.com", I found the service-manual for a fairly cheap price(in comparison with other sellers). I filled in some questions, payed the order with Ideal, and within 24 hours I had my service manual. I was very happy:In no time I had my service-manual and everything, but literally everything was noted down in the manual; the electronic scheme, the parts list, etcetera.
A very practical, reference-document.

AM Tracking Adjustment
loop antenna loop antenna (Supplied accessories)
AM RF SSG set 30% amplitude modulation by 400 Hz signal AM ANTENNA terminal (TM1)
60 cm
Field strength dB (µV/m) =SSG output level dB (µV/m) �26 dB.
Procedure: 1. Tune the set to 600 kHz. 2. Set the output of AM RF SSG so that the input level of the set will become 60 dB (µV/m). 3. Adjust L104 so that when the waveform on the oscilloscope is maximum, no noise appears. 4. Tune the set to 1,400 kHz.
5.
Adjust TC102 so that when the waveform on the oscilloscope is maximum, no noise appears.
