My RA-113 (5) is my 3rd DuMont. Had an RA-111, and another that I had when I was a kid. I couldn't get the first one to do anything other than light the tubes. It had been in an abandoned house and had been rained on.

I've never seen a replacement flyback for these. The flyback in my 113 runs very cool. I let it run for an hour, watching everything like a hawk, and after I turned it off and discharged the CRT, there was almost no heat from the doughnut.
