Couldn't you just whack together some ferrites into a flyback, wind your own secondary, rectify the output, and power with a good ol' Mazzilli ZVS driver? I've got 200watts out of a homemade flyback with a ZVS driver with an output at about 3kv. It drew 9A @24V. Used it for charging my coilgun cap'-bank.

Interesting hack, putting a series limiter ie resistor and multiple capacitors in parallel.
I managed to do this once with CCFL inverters, while each would only output some 2KV at 12mA 8 in parallel would vaporize a steel pin!

Haha, neat. im working on a driver for a load of transformers i had custom wound. 2kV @ 1A out on each of them @ 50kHz going to put 3 in series and 2 in paralell for 9kV @ 2A when i have enough money to order 4 more :) Can't wait to get them up and running.

I calculated that in fact 18 off the shelf CCFLs with the gnd returns tied together with 2k2 balance resistors would with additional work (cough 2 stage CW inverting multiplier /cough) power a magnetron for my HTSC work. Much easier to control, and instant on/off with no overshoot.
DIY 12V microwave would be cool although 18V@9A would be pushing the diddy little 2SD965s near their thermal limit with some heatsinks this would be just as reliable as the Panasonic inverter but 1/2 the size.
a nice use for a TV backlight board or two... I have some laying around and I had a look at a nice magnetron sputtering video a couple days ago... :)
