Re: A new mini-coil competition winner!

Hi Mike,
You're right, of course. I was finally able to scope the gap firing,
and I found this: At low variac setting (25 - 40%), the gap fires
less than 120 bps. At mid variac (~ 40-60%) gap fires exactly every
1/2 AC cycle. At high variac setting (60 - 100%) the gap fires twice
in quick succession, then rests until next 1/2 AC cycle. I tries
measuring the current with my kill a watt meter, but it is
overwhelmed by the RF hash on the line and shuts down. With no
secondary or caps in the circuit, the NST draws about 140 - 168 watts.

With a resonant cap the bps is probably alot more than 120.
Measuring the primary current draw would help.
