I have a secondary that is 4" PVC and the coil is 18.5 inches long.  It is
wound with 21 guage wire, enameled.
The tank circuit is a 15Kv 30ma NST with a .0049 Mf bottle capacitor.
It uses a RQ gap with 4 gaps.
My terminal is a torus 4"X14"

What type of primary would work with this?  I haave tried the following,

1) 12 guage house wire 12 turns vert. 8 in. diameter, 8" sparks
2) 1/4" copper tube flat spiral 7 turns from 5" to 16", no output
3) 11 guage enameled flat spiral 24 turns 5" to 16", no output

I need a lot of help in this area, Please help.   M. Andrus
