[TCML] 60ma Coil Discharge - comments welcome

[Bert Hickman]

Hi Steve,

Your strike ring is too high. The resulting high E-field between the 
ring and secondary creates "Christmas Tree" corona between the secondary 
and strike ring. Lower the strike ring a couple of inches or eliminate 
it entirely.
