37-11 RF Unit schematic differs from my radio
#1

Hello all, I'm new to radio restoration so i'm making a lot of rookie mistakes.  But I'm also learning a whole lot! I've been restoring a 37-11 and have been having some problems. As part of making sure I didn't incorrectly wire something, I've been tracing circuits. So far so good.  But the R.F. Unit schematic I have doesn't match with the circuitry of my radio.  I'm using the John F. Rider Models 37-10, 37-11 schematic.

Is there an more updated version?

So far I've checked all coils, transformers, and made sure resistors are all within spec or replaced. All wax caps and electrolytics are replaced.  All bakelite caps are checked or replaced.

I'd try replacing the bulb first and if that doesn't do it, then change the 35Z5 and see if the problem goes away.NostalgiaRadioTime — 12:28 AM
