No Worries! I'd much rather work on these that one of those confounded ZTO. It's a nice compromise between working on the later 37 and 38-116 or '690. From an electronic standpoint it's a pretty straight forward circuit w/o the frills of afc or variable IF bandwidth. After you get the paper caps done and check the resistor for tolerance then test the tubes. With the issues you've already found they don't stop you from giving the set try. The output transformer will work w/one side open and it won't damage output tubes. The ant coil will probably lower the reciever's sensitivity but it's got a lot of sensitivity so don't think it's a showstopper.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
