Wes,

Actually, David is being kind.  That radio is pretty useless, and the tubes it uses are hard to find.  The thing will drive you nuts trying to fix it.  You don’t want to be driven nuts, do you.  No, you don’t.  So just ship it to me and I’ll save you from the pain and stigma of being nuts.  I’ll pay shipping.

HAH!

No, I don’t have an R-392. I think that somewhere I have a partially disassembled module from one, but I never had a whole radio.  Here are a couple of notes about it:

- The filaments will run ok on 24 volts, but if you separate the “plate supply” connection and make sure it gets 28 volts or so, the thing will run better.  Apparently the improvement in performance is quite noticeable with full plate supply.

- If the outside is cruddy, just wash it.  It’s pretty waterproof.  The INSIDE may look pristine, since it was made to be quite well sealed up. Imagine life in the back of a jeep during monsoon season.
