How do you 'know' that your MMC is OK. It might be full of holes
like swiss cheese and still be 'OK' but impaired in terms of
capacitance and other variables resulting in reduced TC performance.
It might be hard to test however. MMC's are generally thought to be
bullet proof and can tolerate many punch throughs but they may not
last forever.
Other causes are shorted secondary turns and arcing inside the
secondary. I doubt that clean or dirty gaps make a difference
provided the gap is the same. The oxides don't really build up on
the arcing surface, but adjacent to it.
