Hello fellas, I found this 1953 Westinghouse tube radio in the trash and want to turn it into a mini Tweed amp. I was able to get it to work by putting the guitar input into the volume pot. My question is that the best place to do it? Here is a schematic it’s not the one I have but it’s very close. Mine is a H837L5 the schematic shows a transformer which mine dosent have. Thanks for looking.
