[Hammarlund] HQ-120X no audio

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
