Well, as I have mentioned in other posts, my MMC has a
1hr.+ runtime behind it and has suffered NO ill effects. If I
were you, I would be concerned about the amperage your
caps have to deliver. As you are only using two strings,
each string has to supply 1/2 the total current. W/o knowing
your exact specs, I can only give it a guess, but I think around
150-200A primary current isnīt too high. This means each
string will have to deliver between 75 and 100A. Might be
a bit marginal.......... Also that 13nF cap is only about 40%
of the max cap size that your xformer can power.
