Philco model 50
#11

I have now replaced all caps (including backalite ) plus resistor in one of them. I have checked all resistors with a ohm meter. As well, all tubes have been checked with tube tester. All tubes light up, so the filiaments are ok, as well as checked filament voltage of 2.5 volts.Thinking maybe my speaker is faulty, (as I get nothing out of the speaker) I measured the resistance on the outer connections of the speaker at (1194 ohms) and the inner at 353.6 ohms. ( Note I had the speaker disconnected from the radio when taking resistance measurements). As far as voltages across these points, I measure 57 volts dc across on the outer pins, and 14.2 Volts dc on the inner. If anyone has a suggestion on where to start next, it would be greatly appreciated!
