Use Firefox for Javatc if possible..

I have had no success getting JAVATC to run on my computer here at
work. Will try again next week, when I have more time.
Yes, 24 electrodes would probably be better or I suppose I could run
the disc on a belt-driven jack shaft with a 2:1 increase ratio.

Your system looks more or less Ok, but I have a few comments.
start with the spark gap, with that configuration you will be getting
BPS. I think this is low, but I haven't actually done the math. You
to shoot for your cap to be between 60 and 75% charged when the gap
so 30A*120V is 3600 Watts roughly; hmm, gut feeling maybe that is Ok,
you should check it on JAVATC to make sure. Also take in consideration
ballast current etc, will you be drawing a full 30 A or less? My other
comment is on the construction of your tank cap, I think it would
you in the long (and possibly the short run) to increase the voltage
of your tank cap. 14,400/.707=20347 peak volts, which is really
the 24kV your tank provides, I think the rule of thumb is you want
or more of your peak volts, which would be closer to 40K. If you don't
wish to mortgage your house to buy caps, speed your break rate up
substantially with 24 electrodes and provide active cooling for the cap
bank, that way you still get 70% ish charge on the tank cap per
with a smaller capacitance and a much higher voltage rating. A
in Java TC could help with this I think, just to make sure everything is
balanced from a power draw standpoint. Just my two cents...

Finally got around to the initial planning stage of using my potential
transformer to power a new TC. Here are my basic component values
what I have on hand:
Power Supply - 14,400/120 GE potential transformer. Plan on starting
a 30 amp breaker.
Capacitor - .062uF, 5 strings of 12@ .150uF 2000vdc
Primary - 14 turns of 1/4" cooper tube
Secondary - 8.5" dia.x 36" PVC, 1200 turns 22 ga. for a winding
Gap - ASRG, 12 electrodes on disc running at 1725 RPM powered by a
DC motor w/AC controller
Toroid - 24" x 6"
Of course, I would like to obtain the longest spark length possible.
is my initial starting point. Any input will be welcome and greatly
