I was wondering if anyone has any information on this radio. I am needing a schematic(SAM's) if possible. I did locate a copy on the web but it is unreadable. Any assistance would be appreciated.
Hmm..I agree it's not the best but you should see what I sometimes repair old radio's with.
Maybe some photoshopping could improve the details.
What's wrong with the radio?
The transformer is open. I was wanting a better schematic in order to calculate the current needed to run the radio. I don't have it home yet so I don't have any transformer numbers or anything like that to go on.
Owner was wrong as the transformer checks ok. The output tubes are bad as are several capacitors and resistors that are unreadable at this point. I do need a readable schematic at this point in time to repair it. This radio is built like a tank.
