I recieved this Audio Q amp in for repair. The power supply fets are missing but i believe the orginals were DFP50N06's with 47 ohm gate resistors .

Is there a good sub to The DFP50N06's??

Second question is The rectifiers are missing out of the amp beside 1 which is a FMG22U will the FMG22R and FMG22S be good replacements??

Ok I put the new power supply driverboard in the amp. Pulled all of the outputs out of the amp and have 1 power supply fet per bank in the amp right now.

I power it up through a current limiter amp idles around 6 amp of current and the fets heat up in about 30 to 40 secs.

Any idea on what to look for next?

Sorry on the Z44's middle leg would be the drain leg. With the drain leg disconneted this is what i came up with on the gate legs of the fets.
