Re: [TCML] Tesla Coil Computer Interference

[Gary Lau <glau1024@xxxxxxxxx>]

Oooo - not a good sign!  I would have guessed that using the dummy load
would have been a more benign case than normal operation, since there's no
RF oscillations without a primary.  I'm at a loss to suggest a fault
mechanism.  Any possibility the primary circuit or dummy load could have
made contact with the mains?  Is the PC still dead?
