17C9 tube in a Philco??

You could have a burnt resistor, a bad coupling cap in the FM section, a bad antenna connection (probably uses the line cord as an antenna), or an open interstage transformer in the FM section. Or a bad solder joint or PCB trace.

Having fun yet? I love old radios with FM but they are a PIA to get working right. I got several deaf ones to prove it.

When switched to FM, there is no sound whatsoever. Not even a crackle.

Have my DMM, next thing to do is check for plate voltage on the 17C9. Pin 10 of the 17C9 (which is a cathode) is tied right smack into ground. Should a cathode be tied directly to ground like that?
