Chris,

You've got lots of questions in a wide variety of areas, but you may be
going astray in a couple of areas. Are you using any design aids (such
as WINTESLA or similar) to help design your Tesla Coil systems? I'm an
experienced coiler in the Chicago area. I also do high power pulsed
magnetic field work, such as can crushing and quarter shrinking. What
are you planning to do with the widowmaker 300 pound pulse cap? Please
give me a call and we can save each other LOTS of typing.

Re: the above - the 12kV and 15kV could be
paralleled, but two 12's or two 15's would be even better.
