the opening of a static to wide can strain the transformer you are running
and this is probarbly what killed it you can set your gap up right by
connecting across the transformer only then setting so the gap will just
fire any more than this will usually cause failure
if you are lucky you can heat the nst to cure the carbon track in the
potting solution
if not you might have blown a winding i blew my mmc doing the same as you
with my gap
