Hi All,
I fried my 4.5" coil last night, I was getting 80" strikes at 14Kv :). But
you all know how it goes from there---MORE,MORE,MORE. So I flipped the
switch and fed it 24Kv. It went up like a 4th of July sparkler ;( !!!
Well now to build a \\BIG// coil, I have a 120/240--14,400/23,800--10Kva
pig, 2 max-caps 45KV/30nf each. I want as large as the PS can handle. So any
Thanks for the input.

Wow, that is a lot of power for a 4.5" secondary. 80" is good performance for that size coil. The most power I have fed my 6" coil is about 7.5 kva - and I don't think it can take much more. With the power supply you have available, I don't think a 10" or 12" secondary would be out of line at all.

So, did the secondary develop racing sparks and burn up?
