Re: Fire on the jag
Bob,
The chances of four Jags having a failed Q4 are staggering. How are you checking the FETs? They should show a high resistance from the gate to the other two leads. When measuring the other two leads, they should show some resistance in one direction and a lower resistance in the other. You should be using a multimeter set on the diode test range.
If you look at the schematic you will find that Q4 and Q5 are in parallel. Are you sure that C42 is not shorted?
