Re: [TCML] First light (maybe second light) on mid-sized coil

Hi DC,

Yes, but if I use two separate 120 volt circuits, then I'd be,
in effect, using 240 volts, which was what I was originally
trying to stay away from on this particular coil. After all,
all 240 volts is a 2 separate 120 volt circuits 180 degrees
out of phase with each other, with a mid-point nuetral. It
seems that I may have designed this coil a wee bit too big
to feed comfortably on a diet of a SINGLE 120 volt circuit ;^0
