A friend has given me a General Motors Radio. This is not an auto radio as one might suppose. It is a floor model unit with a phonograph in the top. The radio looks to be a TRF unit, I'm guessing. The whole thing weighs about 200 lbs. I can see it is an AC set with a large transformer. I see a 45 tube and several 24'sThere is a tag on the back with: General Motors Radio SN 64506A. On the lower back another tag: Model 450A.
No problem I think. I looked on the site and found what appeared to be the scheme for the Phonograph But
among the many radios I can't find the one I have.

I wonder if anyone could help me find the right schema.

Hi Ivan

Here is a GM radio with 45 and several 24's.

If this isn't right list all your tubes.
