Thanks Stefan,
I may end up going that way, we will see.
Nice supply, time to make that coil! I made a 3 phase MOT coil a few years ago also.
It's detailed here:

Hi Greg,
is there any reason why not just use a Maxwell Cap with these specs? By
the way, 3 years ago I have built a similar DC resonant charging system
(still without primary / secondary coils, but charging system works very
well...). Have a look at my video:
