Im needing to know some replacement part numbers. Its number on the board is r238 it looks like a big resistor. I also need to know were i can get the irf 540 part number ive found slot of those but they were ifr540n and i hear there not good for these amps and i also need irf9540. Any help would be great.
Can buz11 transistors be used instead of ifr540 and ifr9540
Not really. You should stick with the original design and parts for best results...
