( given the spirit of VR) a case for something like the old TL494 SMPSU regulator, or it's modern day equivalent ( something for the up-to-date blokes to work on). Works well enough at 12v in ( or possibly higher, as I used it as an HT source for a Xenon strobe).
Problem with mine was finding a transformer working at the frequency . I made one from a circuit I "developed " from an old GEC telecoms design. Circuit must have been reasonably noise free, as we noise tested the power rails for harmonics. I never tried the capacity of the output, but I did have this circuit running an old light box of one 8w tube ( albeit through dropper resistors to drop the HT after strike). I did mention this in some past posts, looking for an equivalent for a ferrite core, and someone suggested a transformer out of an old laptop PSU.
sTATION X - ( as said in a vintage TV program), if you can find TL494 then there's an idea to work on.
