It does appear the gate and drain pins are shorted, out of curiosity, how does this kill the chip?, as i'm looking at this thing and it looks like the chip is driving the MOSFETs through T1, which i would think would isolate the chip and MOSFET.

On top of that, could i use a different MOSFET/Transistor for testing this thing, I have a ton of salvaged MOSFETs from PSUs over the years. So if i install a used one and the chip kills it, then i will know if the driver is bad?
