Mark,

I am seriously impressed with 25 foot spark length.  Is this with 18kv input?
 Are you using two capacitors in the primary, one to each side of the primary
coil?

I think you are correct, the only way to increase the output from my present
system is by raising the input voltage.  This is difficult since I have a
14,400 volt pole pig and a 15,000 working voltage primary capacitor.  I would
be most interested in your efforts to build a voltage doubler that can stand
up at these voltages and currents.  Keep us posted.
