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.

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.

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.
