FWIW, I've just desoldered the legs of the power FETs, tacked short
wires into them and plugged them into my little component tester. I'd
say the results suggest they are ok?

(Looking at the FETs left to right):

The 2 nd from the right To-220 looking FET seems to be shorter than the
others. As the back of the FET is the 3 rd leg should it have a wire
connecting to that long pad above it ?
