[Larry N. Carman]

On eBay there is a listing for 'DE 330uF/450V ELECTROLYTIC CAPACITOR! 200
PCS'. Here's the link to them ->

&item=7567589136 .  Would 12 of these capacitors suffice for a  1 amp 4000
VDC amp supply? I have ran 16 of these in a 4000 volt supply at .6 amps
without a problem but I'm limited on space with the current amp I'm
building. Can they be mounted in close quarters?
