I'm restoring this system with the original dyno, junction box, control box..

I built the cables , hooked it up , but the audio is extremely low and I think the TRF stage or stages may be breaking into oscillation.  I haven't done any real troubleshooting, but I know the dyno module is OK.

TRF radios can be finicky, so i was wondering if there were any hints as to what to expect ?
