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
