In a message dated 98-01-15 17:05:37 EST, you write:
 I have a custom-built control panel that I use to run all of my
 and "just for fun" coils.  It has a spark gap-HV interlock circuit, and
 massive Filtron inductive/capacitive filters between the power input
 and the rest of the control panel.
 I don't usually use any filtering or protection between my HV
 transformers and the panel, but then I've never observed the problems
 you have.  I always make 
 certain that my control panel is tied into a heavy (&short!) safety
 that is _separate_ from the ground used for the secondary and HV parts.

I also use a separate ground rod system for all the 60 HZ grounds.  I have
this connected to the line filters, variac cases and most everything else in
the control circuitry.
