Re: [TCML] Tesla Coil Computer Interference

I just noticed - you said your NST case is connected to the Variac green
wire (mains safety ground).  This is wrong, IMO.  The NST case should be
connected only to the RF ground, although there is some controversy here.
But this still doesn't explain what zapped your PC.
