Hello,
I just purchased a "restored" HQ-120X. Cosmetically, the case, panel,
chassis, etc, looks like it was just manufactured. The electrolytic
capacitors have all been replaced, and so has a great deal of the wiring.
However, there is no audio output. I do not have a schematic right now. The
radio appears to tune, as I can tune to a known station and see the S meter
deflection, but it appears that there's nothing on the audio stage. I
removed all the tubes and tested them, with no issues. I don't have a VTVM
anymore to go poking around, so does someone have a schematic they could
email me, or possibly give me an idea which components that may be "known"
to go bad in the audio stage?
Thanks,
Darryl
