I would like to share my trick in replacing the mosfet from pallet amplifier which I learned from my experiences in pallet fabrication and repairs. Most of us would like to unsolder those mosfet legs first one by one and is the most difficult to do since too much heating on those pcb pads would accidentally delaminate the copper from the board.
My shortcut in doing this is to cut the legs of the mosfet using a cutter blade but before doing this please make sure that the mosfet is verified defective!
After freeing the mosfet, now unsolder the remaining mosfet legs from the board using a soldering iron. Cleaned the board, apply fresh thermal paste and mount the new mosfet. 73 de du1vss
