I currently have two strings of MMCs. One with 15 caps and one with 16 caps.
Each cap is rated at 1250v, 0.22uF. I'm using the 16-string with my 15/30 NST.
Since 1250x16 = 20 000, I'm not leaving much of a safety margine.
 
If I were to use a 15/60, would I seriously be jeapordizing the life of my MMC?
 
What about about a 12/60?
 
Thanks,
Patrick.
