Your project sounds impressive. I hope we get to see some pictures of
this beast!

I have a couple of questions though. I recently tried a relatively large
sphere on my (small 900VA) coil. Its capacitance was 32pF as opposed to
20pF for my toroid and while the spark length increased somewhat, the
field control was terrible, i.e. I had to put a discharge pin on the
side to prevent the sphere stiking to the primary and the ground all the
time. Is there some reason you chose a sphere over a larger diameter
toroid?

Also I have been planning my next coil as a DC system for some time but
how do you rectify 130Kw?!! Do you believe DC Tesla coils are inherently
more efficient?

Cheers, Petere E.
