How are you getting these?If elecctrical parts are cheap in your country 
why not get a small substation trasnformer and an ex laser cap bank and 
REALLY go for it ;)
You know what we in the tesla list should do? get a large container shipped 
from croatia full of cheap transformers ;)


It also seems to me that if maxwells are putting up with a lot of abuse, 
good; but maybe a pole pig would be better suited to it than a potential 
transformer.

What happened to your last one?
