Hi, I have this amp to repair.
It is a 4 channel Mosfet amplifier shorted causing the fuse to blow and a PCB track interrupted.
A few years ago my brother took him to a boy to have him repaired but he told him that the transistors are not found.
I would like to try to repair it, but I noticed that a couple of mosfets are missing on the power supply circuit, the ones next to the SMW60N06 and I don't know if the missing transistors are always SMW60N06 or they are different.
Does anyone have any advice for me ?

For the power supply FETs, the IRFP064N should work.
There appear to be 4 PS FETs, you need to replace all 4.
Are any of the FETs in the amp now shorted?

You need to replace all 4 if you want the power supply to be reliable.
Do you have an oscilloscope?
You need to check the remaining FETs before you do anything else.
