Hey, can you give me the dimensions of your coil, height and diameter in cm. or inches as you wish? I've got a pretty accurate formula for parallel resonance and it might be useful to calculate self-resonant frequency as you don't have a scope!

Arcing can be a pain and destructive. Where's it coming from this time?
