The flashing over was at "a secure, undisclosed location" somewhere near
the midpoint wire. That
was part of the problem.

Well, for that much current out, you need big current in. So the primary
could be just as much a
problem. For 15KV -at- .500 AMPS , using 220 VAC in you need 34 AMPS primary
current.

Would be impressive!

Yeah, it was really old craft paper construction. They only shellaced the
outside, no vacume
impreg., so I set up a winder backwards(unwinder) and recovered literally a
mile of 28 AWG wire. I
have wound a couple of TC secondarys with it.
 Still it could be usefull for lower power TC's. Depending on the wire size.
