Here is what I have. A small coil 2-7/8" dia secondary ~13" long topped
with a 4"X15" dryer vent toroid, primary is 30deg spiral made with #10
ground bus wire as you mention below, about 15 turns. I get somewhere
around 20" streamers with a 12KV 60mA neon and 5 static gaps.
The primary caps are not the best for TC, they are barium hockey pucks
from a laser supply.
Where on the performance chart does it go?
