Got inspired to build this a while back from Brian @ SciTubeHD's videos.
Pair of IXDD614CI's powering a GDT to drive the bricks. Not sure what I'm going to do about a resonant capacitor though so might have to do like others and stack a bunch of small ones on plates. So far it works ok with the driver not really being done yet so that's cool. I haven't decided on the best approach for feedback but I'll probably research more into what has worked for others before finishing it. I also didn't try to impedance match anything and just wound a length of wire I had on the toroid for the primary so it does seem like a toss together can kind of work. I never felt any heat accumulating on the primary wire at a tested max of 250W.
The coil is about 2uH and the caps add up to around 3uF. That ballparks to the 65khz range. I basically just need to find some kind of crucible I can put in it for testing higher power to see if I'm able to do enough over 1kW at ~170VDC. Otherwise the idea is to just use the 3p rectifier and feed it 3p 208 for close to 300VDC. Either way at only 120VAC on a 15A circuit it seems like an easier approach to 1kW+ than a ZVS driver unless you already wound some high current step down transformer for it.
