PVC is lossy and not recommended.

Is the transformer self-limiting?  If not, you can probably coax at least
another 20-40% out of it.


---> No, the transformer is not self limiting.

It will drive it just fine.
What is the dielectric material of the cap?  If this is a typical oil type
capacitor or one used for power factor correction, it is ill suited for Tesla
coil use and may even EXPLODE!	Capacitors should be of polypropylene or
polyethylene dielectric.  Mylar is OK in a pinch.


---> I am not sure what the dielectric is.  It is in a rectangular metal
case with a huge ceramic insulator coming out of the top center.

Thanks a lot for your comments Mark!
