Randy Peterson has 4 large caps of .05 uF each rated at 75kV.  They are
cylindrical with a diameter of about a foot and a height of 18" with
black cases.  They are from an old particle accelerator.  He's asking
$100/each.  Is this a good price and what kind of cap would this be and
would it be suitable to use in a TC? I should think with their huge
voltage rating and large size they would be practically indestructible.

Incidently, I also got a 70uf 10kV cap from him and want to do can
crushing and the like.  Could some kind person who knows about this
stuff email me off list at sdarling-at-columbus.rr-dot-com?  Thanks!
