   Hi all,
   
   Here is a nice doc on toroids.

   HV capacitors
   You can buy HV caps, but they are extremely expensive.
   You can choose to set some lv in serie.
   Here is the formula:
   
   Totall capacitance = (C1xC2)/(c1+c2)
   2200 uF 25Volt + 2200 uF 25 Volt
   Makes: 1100 MFD  50 V

   if you use the same caps you can just divide the capacity of one cap by the number of caps in series.
   
   example: 4 caps with a capacity of C1 in series, then the total capacity is C = C1/4
