Chose this radio as it is as simple as it gets.
Just finished a complete rewire, recap and resistor replacement for a Philco 84. Unit powers up, but no audio.
I also had to repair some coils, but all ohm out ok now so I know they are good. Used 20AWG, solder joints are clean and checked. Continuity checked connections around and all are good.
Transformer is 199 on one side, 215 on the other and 425 in the center
5v and 6v on the filament sides.
First power on started with a bad rectifier tube, which promptly blew out the 10f Electrolytic (Nice puff of white smoke) , but put in a new 80 and that problem has stopped.
What could be the common cause of No Audio ?
I truly appreciate everyones help here.
