[TCML] Looking for Pole Pig Capacitors

If you only lost one of four, and you can't find a suitable large cap, you could consider buying one more 37667 and going series/parallel (assuming the other three caps aren't bad). I've run my 37667 in series/parallel for years at pig power, and never lost one. You'd have a smaller cap than you want, but assuming you can still tune (more primary taps) you should still be fine.

Subject: [TCML] Looking for Pole Pig Capacitors
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.
