I killed my first neon this weekend and it wasn't opening the gap too
wide that did it either although I was pushing it a bit. Ironically,
it was the first and only time I've ever run with a safety gap
(which was firing with *low* energy at half an inch setting). I cooked
half a winding (partial short). I've finally discovered the mechanism
responsible for this. I am going to unpot it (reheating the tar
didn't work) and may wind something much more robust. That core is
huge for the amount of work a typical neon actually does.
