Default Soundstream XTA-480.2 repair direction

I recently acquired the noted amp as part of a package deal. $30 for 3 amps, one working Jensen, the SS, and a Targa that may or may not be revivifiable.
Being stuffed in a box, the exact number fails to come to mind right now, but there are at least half (4/8?) of the IRFZ44N devices on the PS side that let the smoke out, and one of those (that I recall) has turned the PCB trace into a blown fuse configuration.
I have not been able to find a schematic as yet, and am still looking.
So besides the obvious mosfets, what are the next obvious parts to check?
Tools: a couple basic DMM, one RadioShack unit that does the usual measurements, and one 7 function that has the hfe tester for transistors.

no parts have yet been swapped or exchanged.

The PNP driver transistors and the output transistors need to be checked.

Finally got around to it: Everything checked out per DMM tests (output trannies are not matched all that well), swapped out the power MOSFETS, and it powers up and WORKS!!

Thanks Perry.
