Turns out....that 50UF cap must be bad. With it in the ckt...the voltage to it drops to about 50 volts and the 1.8K resistor feeding it smokes. With it OUT...the voltage rises to about 120 or so volts and the resistor is OK. But it does NOT measure shorted on the DMM.. Must be badly leaky I guess...when voltage hits it.

Chassis DOES work--to some degree now. BUT...it does NOT seem to have much volume-- even on the sum channel--compared to that nice Silvertone I have here now--and showed in another post--the one with SE 6BQ5 amps. Also--the stereo light does not some on, blinks sometimes--but does not light steady no matter what. I realize the Silvertone is a lot more powerful...BUT this Philco seems REALLY weak. SOME him---but not a huge amount. Main B+ seems pretty close to the 140 volts shown on the sams. AND==when I finger the phono input...it is a LOT louder--for a couple of seconds...then fades--since the amp shuts down due to the power going off(must be switched by the phono in that position).

If that 50UF cap is not in the CKT...would it make THAT much of a difference?
