The caps/leads/everything is prbably close together... try sticking it in
oil :)

TCs are wierd beasts sometimes!!! I got a 2" flashover from my caps to the
RF ground - Im not sure how it worked, probably from the ground to the caps,
not the other way round - explain that if you will!!! But you will find very
strange things happening that you will never be able to explain...

Good Luck,
Jason
