MMC Fans,

I replaced my MMC on my coil with a commercial cap and gained an extra 10% -
15% performance increase...

1.1kW NSTs (Tunewell)
4" sec, Res. 285KHz with Topload 21pF
20nF MMC (Panasonics) replaced with 20nF TDK-UHV 9A's
300 BPS SRSG breaking at 60, 90 and 130 degrees (wierd, but seems to work)
Usual filters, grounding, etc.

I was surprised by the unusually high performance increase, which was max.
45" with the MMC, and sometimes over 50" with the TDKs. I put it down to the
extra resistance by the MMC leads, the resistance of the primary circuit now
being almost nothing with the introduction of copper bus bars to directly
mount the caps.

Just like to plug the TDKs - they seem to work pretty well!

Best Regards,

Jason
