Philco 89 Questions
#8

Check for shorts in the speaker field coil? I also had a Gloritone with a weak '45. All the plate and screen voltages were high throughout the radio. When I replaced the '45, everything went back to normal (about 250V for the B+ to the output transformer). Is your '42 good?

I know that modern DMMs have much higher input resistance than the 1000 Ohm per Volt meters of yore, but I don't think that an old 1000 Ohm per Volt meter would load down the plate and screen voltages of the output tube that much when compared to a modern DMM. Other measurements, all bets are off.
