Mwa Ha Ha, a class D tube amplifier! 😀

Hey, super! 🙂
What about making the output SRPP or a CCS in place of that big ugly resistor?
Cheers!

Very clever and impressive! It reminds me of some stuff that Crowhurst was doing in the 60s.
Dull old me would have done something very conventional and boring with 6GF7 in p-p or something like that. Yawn.

SRPP would be half bridge, which would be two 38HE7 stacked, using the damper diodes antiparallel to clamp flyback. Essentially what I have now, in parallel with its inverse. It's harder to drive. Push-pull is easier to pull off, and equivalent in operation, however. Too bad I only have the one 38HE7.
You're right, a CCS could be used, about doubling AC output. But it's hard to make tube CCsources, and I don't have a 200mA * 160V tube that could still be used in the contest.

Somebody finally found a use for those things! Good thing you haven't published your address - you'd be carpet bombed with 38HE7s and 53HK7s...
Hi Tim,
Right!
For some reason I thought you were developing this beyond the contest, but it ain't over.
Cheers!
