The problem was I had WAY too much cap in the circuit. I pulled 2 of the 6
strings and the cap sings as it's stuffing 46.5" arcs through the toroid to
a grounded rod (that's todays' measurement).
Here's a scribbled note from a couple days ago I picked up off the floor.
"6 strings
per cap 2kVDC
.1uF
9 caps per string
4 strings
tapped turn 7
4"X30" topload
breakout, 44" sparks to grounded rod"
kinda says it all :)
My sec is 6"X39" 22AWG closeound, what the resonant freq?
Have Fun!
