Hi all,
I have this amplifier in protection. I have noticed the power supply caps are leaking.
what are the correct mosfets for the psu / output sections?
the amplifier was previously repaired

Hi,
Its not visible in the pics, one is swollen on top, other is leaking on the side...
Amp model - Terminator 1000.1

If you pull the rectifiers, does it go into protect?
^^^ Some of these have a drive/rail sense protection that will shut the amp down if it doesn't see rail voltage being produced. For those, you have to disable that protection. Pulling the rectifiers will prevent it from producing rail voltage and that will trigger the protection circuit. I'd need photos good enough to read the markings on the SMD parts to be able to tell if your amp has the protection circuit described.
Leaked electrolyte can cause all sorts of problems. That needs to be cleaned up before you can do any troubleshooting.
Some used the IRF640 and others used the IRF640N. There may have been others.
For the PS, I'd likely use the IRF3205 with 47 ohm gate resistors.
