*Before 55% on the variac, i can clearly hear hissing and high voltage corona coming from the coil, but in pitch dark, i see NO sources for the sound
*Coil starts up at 55% power.
Can somebody help me. I want to regain the ability to controll the coil. Any suggestions or solutions? Please respond ASAP. I am using my coil for my "Senior Success Seminar" for my high school(need to pass to graduate)


The hissing is probably a carbon track. Carbon tracks are not limited to wood, they also on other materials. I've even caused a 5" carbon track on G10 composite. Since total darkness isn't unhiding the source, use a flash light and make a detailed visual inspection. I personally would be looking for a carbon track.

Take care,
Bart
