Replaced the power supply fets with IRFZ44's And replaced the outputs with IRF540's.

AMp will power up and play fine for about 2-3 mins then the output gets very low and you can hear static through the speakers with or without the rca jacks plugged in Any ideas?

After removing the caps and cleaning the board, shine a bright light through the board and look at the traces with a magnifying glass. You're likely to find that some of the traces have been eaten through. It's difficult to tell without shining a light through the board. If the electrolyte has flowed under the ICs, you should remove them also so you can clean the electrolyte and examine the traces.

If the board's not repairable, try emailing the ebay seller dealsbyjason.
