Might work too well? When tuning a classic coil, we change tap
location by fractions of a turn, maybe small fractions of an inch in
mutual L tuning system . . .  But I really like the idea :-)

I looked at Richardson Electronics, http://www.rell-dot-com, and they are
"on order."  I ordered some other caps from them, and it took about 1
and a half months to get the caps that were on order (0.33 uF, 1600
V), but they are relatively cheap there.  Just search for the part
number that you want in their online catalog.

Good luck with the OLTC project, hope it works out, a 20 lb complete
Tesla coil, Hmmmmm.
