Hi Aaron, I did manage to blow expensive block Mosfets with very little load, hence relatively small switching current.
The pull down resistor was 10kOhm, same size as on the EG002 board.
It may take a while but we try to get to the bottom of these failures.
I have now a little inductance meter (cheap on Ebay) so I can measure what inductances there are in play.
