There's another variable :)

A Tesla Coil is a finiky balancing act and if you want a bigger cap, go for 
it. You can have your cap AND your primary turns too, just change your 
topload size.

a formal place to play the bongo drums, the introducer never seems to find 
it necessary to mention that I also do theoretical physics.
