Ed,
I just got some 1.0 mF 2500WVAC MO caps that I am planning to use to drive 
an ignition coil the way you describe off the 120 mains in series with a 
600 watt dimmer. You say you pulled 30 amps. Did this trigger your circuit 
breaker? Are there any "anomalies" I need to look out for that you can warn 
me about?  My ignition coils are very robust racing coils from my drag 
racing days. Three of them are rated at 50 kV and one is rated 60 kV. They 
are much larger than standard coils and contain a lot of cooling oil. I 
believe I can stress them pretty hard without worrying about burning them 
up. Even if I kill one, I have 4! You mention line glitches. Do I need to 
put an EMI filter between the plug and the dimmer to protect my house 
wiring? Any advice will be greatly appreciated. Regards.
Paul
