Hi Shad,

Your system with the ballast you describe will have a resonant cap size of
110nF.  If you are using close to that value, perhaps the voltage got to
high with the rotary and blew the string.

Also, I am getting 70 - 130 amps RMS in your primary circuit (guessing
stuff).  so that would imply 20 to 37 strings of caps for the current.  I
ask you some stuff of list that will firm the numbers up but over voltage
and over current may be factors depending on exactly what you have there.

Obviously, we need to get this pinned down before you try your expensive caps!

Very cool stuff you are doing!!!

Cheer's
