Well, I would be quite happy if I got 10% more spark from this secondary
alone, but my real reason for my building a larger secondary is to allow me
to use a larger primary cap and more input power. I'm going from 0.01uF to
0.03uF, and I need both a larger secondary and a larger toroid to be able to
tune this system without having to build a larger primary coil (not an
option for me right now).
I had an 8" x 25" x #20 secondary, and I'm replacing it with a 9.625" x 29"
x #22 coil. My old power supply was 9kV -at- 120mA NST, my new supply is 12kV
-at- 180mA from NSTs.
