Hi Roger,

I have a couple videos on my YouTube channel.

Hello everyone!

I recently destroyed a 0.03 uFd  35kv Maxwell capacitor (#37667) of which I was using (4) in parallel to achieve 0.15 uFd at 35kv. I am running a 10kva 14.7kv pole pig powered coil with a 12in diameter, 57" winding length secondary, and a 60in major/ 12in minor diameter toroid. The single capacitor cracked in half and splashed oil for a good 8 feet. Evidently, my configuration was poorly designed to handle the ~ 15 kv input. Apparently, people have had this issue before and I was previously warned by David Rieben.

David suggested 2 of these Aerovox 0.305 uFd 50KV Capacitors in series, but that would be a bit pricey given the shipping for about152 lbs! Yet, I am considering them.

Is anyone willing to sell pole pig suitable capacitors, either single unit or several, for approximately a 0.15uFd  50KV + rated capacitor bank? I'm a student and my budget is around $100-200 and I will of course pay for shipping and handling; I live near Pasadena, California. Please let me know if you have any comments or suggestions regarding possible capacitor choices; they will be greatly appreciated.

Thank you for your kindness,

Amir Mojarradi

Those Aerovox capacitors sound like a good deal to me.   Im tempted to get a couple myself but if I made my coil any more powerful I would have to take it outside to run it.    Your set up sounds pretty awesome.  Do you have any pictures?

Thanks Amir, It looks like your coil is doing really well other than the capacitor problem. I'm running with .08 uf capacitance on my coil. Here is a link to a video of it.
