    Also doubt the mosfets are fried, would check soldering points as suggested. The must probable status a blown mosfet will end in a circuit like this one is short-circuited, so blower symptom for burnt mosfets would be running at max speed allowed by the progressive control (not max stage).

    if the mosfets were cooked would you not be able to pick up a burnt smell and see discolouration on the circuit board surrounding them? i don't have either of these so maybe it is just a case of bad soldering although they all appear to be ok. i dunno!

    Default Not necesarily, but you would probably pick a short-circuit ...

    with an ohm meter from drain to souce.

    lastest info:
    you can use BUZ11, these are even better than the BUZ71 I mentioned in my first info.
    This info comes from my friend in Germany. He is an electronic engineer and has his own company and has repaired a lot of swords for the members of some clubs in Germany.
    So that advise comes not from a DIYer but a pro.
