Model 90 Stuck At One Volume Level
#1

I finished the overhaul of this Philco 90 with the single 47 output and it plays but I have no control over the volume. It's just stuck at one volume level and operating the volume control in either direction doesn't change it. VC bench tests good after cleaning. I've gone over all my circuitry and can't find a problem. The only voltage anomally I see is on the plate of the Det. Amp. Paperwork calls out 140 volts and I have 54 volts. But this copy of the paperwork is a little fuzzy. It looks like 140 volts.

I don't know where to look next and could sure use some help.

Thanks,
Pepper
