Please help!! my tesla coil has been on the back burner for a while now. im stuck finding sutible capacitors for the primary tank circuit. im on a limited budget. factory made caps are very expensive! ive tried the homemade bucket cap route, but it didnt hold up. two of the glass bottles actually shattered in the bucket!

ideally i need 8.6nF. im powering my coil with 15kv NST. so 15000x1.414x(saftey factor of 2)=42.4KV. please contact me if you have some or know of a surplus store!​

Talk to "DerStorm8" I recall awhile back he found a good deal on some polypropolene caps for his TC project.
