Ok, series/parallel pins (bed of nails) between mica (available at American
Sci & surpluss in nice little 2"x 2" sheets) with a fan blowing through

My thinking was, 4 sheets of 50mil LDPE with 1mil silver mylar in between
for good luck. Just 1, big, thick, dielectric.

But wrapping and insulating the multiple windings of the transformer strikes
me as the hard part.
