Hi,
Philco 41-680. I only have very faint sound from local station and nothing
else. Checking the plate of the 7C6 (Detector / 1st Audio) and the voltage
is only about 7 volts. The B+ on the other side of the 220K resistor, #63,
is about 150volts. I replaced the resistor which was cracked but voltage really didn't change.
Just wondering if it should be that low and is there somewhere I can find what votages should normally be at each element of the various tubes in this model.
Thanks much!
Harlan
