Re: Introduction / LTR caps

That chart was designed only for common NST values.

A properly designed MMC will work on any sized Tesla Coil, even Greg 
Leyh's ALF facility.  Multiple parallel strings are used to increase 
the current handling capacity of the MMC.  5 strings in parallel will 
be running about 2160A....  Which, incidentally, works out just about 
right IMO: 15 caps per string, 5 strings, using .15uF, 2kV caps.

In my limited experience, and drawing on Sundog's significant 
experience, with large pig-powered TCs, run 120bps and the largest 
cap you can get to fully charge (well over 1.5x resonant).  But then 
you have to deal with an MMC of about 15 strings of 15 caps of the 
.150uF 2kV CD caps for a ~10kVA TC.

IME, the mounting and soldering 225 caps as well as their sheer 
volume is well worth the expense of a couple used Maxwell, GE, etc 
caps (or even new ones?).

Cheers!
