Hey guys, now that I have some questions answered, I wanted to ask about the coils that are in the radio. This is a 1932 cathedral Philco 71B (single speaker)

There is a R.F. coil
Det. coil
R.F choke
OSC. coil
First I.F. coil

Could any of you guys please tell me the range of Ohms' each of these coils and choke should be at in the circuit when I check them. I need to test each and have a feeling that one of them is bad.

I also need to do a full recap, someone put in a more recent electrolytic, and on a controlled initial power up I didn't pick up a single station with an antenna connected. The audio section is good, I did a in depth check on it.

Thanks for you're help

Jon
