Re: MMC costs

[Terry Fritz <twftesla-at-xxxxxxxxxx>]

Hi Michael,

For a 120BPS static gap with a 12/30 NST, you need about 9uF.

MMCCalc gives about 3.5 amps RMS for your coil and a 2 string by 12 caps
per string (2 x 12) MMC of 0.056uF caps.  there are other possibilities
depending on what caps you can find by MMCCalc2 will figure it all out for
you.  If you have a sync rotary gap, the MMC value could about double.
