I wonder if all I need to do is replace the 8 blown fets to get it working or maybe the gate resistors are gone too..It powers up but has no output..anybody got any ideas?

Replace the mosfets,gate resistors and follow the path from the gate resistors and the small transistors tied to them.Do all of them and you might have to do the tl494cn ic that turns on the mosfets.Everyone i do i change everything weather it is bad or not to make sure for no problems later on.Try to use exact parts with mtx or xtant amps.Also check the outputs because most of the time blown power supply takes the outputs also,even if there are no marks.
