Yes, that was the TC. I had to close the gap right up to get it to
fire with the horrendous air blast. The transformer could only do so
much and charging is non-resonant. With the gap closed up to that
extent, it fired fine with no air or a moderate breeze but the coil
never broke out at all. The transformer is incapable of getting that
cap beyond 8kVpk and that is also a conservative figure.
