I just bought some surplus PFC caps at a utility auction, and they are 
rated at 2400V, 25uF (V too low, C too high for Tesla coils, just fine 
for exploding wires).  I know they make and use higher voltage caps, but I 
imagine that the capacitance would be too high to be of practical use.  
But if you see something that would have an appropriate capacitance and 
voltage rating (2 or 3 x your input voltage?), go for it.  If I can get a 
few more of 2400V units, I have entertained the idea of sawing the top off 
one (no PCB's) and seeing if I can reassemble the pieces into a higher 
voltage, lower capacitance unit (anyone have any experience with this?).

Good luck.
