Well so far I'm finding nothing in the audio circuit that's bad. No caps, resistors etc. The audio transformer resistance readings are per the Philco paperwork. I've never seen a speaker that was bad except for needing a recone but I'll check that too.
I did go back to page one of the Philco troubleshooting guide for this radio. This is the paperwork from Chuck Schwark.
Supposed to have a minimum of 50Kohms from B+ to chassis gnd. I have 22K. Paperwork says to check three capacitors for shorts or leakage. The E-caps and one bypass cap. The old ones were good. Four years old but I installed all new ones anyway. Still 22K from B+ to gnd.
Still pluggin' away.
