I installed 20 irf 3205 fets and 48 ohms gate resistors . Got it working, but blew a fet due to my own error. As we know all will show bad when tested in circuit. The source and drain read short. I purposely shorted gate and drain. Held my dmm red probe on the gate leg and the black on all source legs. all read in the upper 40's except for 1, The bad fet. Is it dumb luck or has this been know to be a way to check for bad fets ?
by the way One of the big black capacitors was shorted to the case.
