Good catch Stan. I just picked up a pair of mosfets at the local electronics jobber, so I will test it out on the breadboard. If it looks like a trimmer pot would be advantageous its easy enough to add. They did not have the IRFZ44 in stock, so we subbed a pair of IRF540's, made by Vishay instead of IR. One thing that worries me a little about the specs on both is that they show the gate-source voltage Vgs as 2 volts min, 4 volts max. Does this mean that the 12 volt gate voltage in my circuit is going to fritz them? Or am I interpreting this wrong?
