Dumont RA-113 (B3) restorations

[holmesuser01]

Do you have a clue as to who supplied the OEM tubes for these DuMonts?

My RA-113 is full of every brand known. I suspect that RCA supplied them, but don't really know.

I've replaced all but 3 or 4 electrolytic capacitors in mine. I've got FM radio to the speaker, but still have not seen a raster on the 17BP4 tube, which checks good with my tester. I'm not worried, though, as every cap I've replaced has made a difference in the way the chassis works. Just replacing those 3 HV caps on this set raised the HV from 1500v to 10,000v!
