Well I installed a 2x3 fet stack of 4562's on the same board and it works using a hakko ESD safe soldering station, static mat with wrist strap. All I can come up with is that the original fets I was going 2 install that I dropped on the carpet floor got zapped by static electricity or they where no good 2 begin with.
