I have a spare torodal transformer and some 4700-100v caps and probably Br-rec that will get you 70+volts if you haven't bought them yet.
The torod is almost new I think it's 1000va but will have to dig it out to get full specs to be sure then i'll be able to work for you the exact volts + amps.
I think i've got 4x caps which can be wired parallel and If memory serves me I think this transformer and 4 caps was giving me around 76 ish volts and 14A ish.

PM me If this is any use to you and I'll give you my contact details.
