Re: LTR&MMC

Hi Tero,

I did a computer study below that generally andwers this question.

http://hot-streamer-dot-com/TeslaCoils/Misc/NSTStudy/NSTStudy.htm

I constantly refer to this data for NST/cap sizing.  The LTR sizes are the
values that give 120BPS operation.  This data is only for static gap NST
systems.

Unfortunatly, I don't think it will be of use in your case unless you can
add or guess you case.  If your trannies are not current limited types, it
may not help at all...

Cheers,

	Terry
