Ok,

Getting away from CD caps, i bought 1200v .68uf GE caps.  I had one string 
of 24 for a cap rated .0283uf and 28.8kv.  I run this with a 15000v 120ma 
PSU.  My coil performs wonderfully, and there is no heating in these caps!  
and heres the kicker, they were only $1.52 each!!!!  They are sold at 
madisound.  Im very happy to see that i have my complete cap bank for this 
large coil for ~38bucks, and shipping was only like 4 bucks.  I also found 
that Allied wanted some $8 for these same caps!  I cant wait until i have 
more cash, i will definitely be buying another bank of them.
