Alllll right!  The "Q4" suggested that it was a transistor, but it only 
uses two pins.  What's the "2S" for?  I'll grab a new transistor from 
Active Electronics and try it.  That is, if it isn't to expensive.  Even 
if the CPU might be fried it's worth a try as an experiment.  The CPU 
did get pretty warm when the power supply would start.

Thanks a lot!
