Hi:
Newbie question, Recapping the above radio, lost all sound 2-3 times after replacing most caps, but seemed to have traced the problem to either tube 7B7 or the 508X. There was no sound but when I jiggled tube 7b7 the sound came back. Further, when I tap the 508X tube the there i a popping sound in the speaker indicating that there might be a problem there as well. There seems to be an intermittent short perhaps. Please help me diagnose the problem so as to resolving the intermittent sound loss. Thanks for the help. Also, part C7 a capacitor, can't seem to find it on the schematic, what size cap is it?
God Bless,
Dave B.
