Im rebuilding the power supply in this amp New fets new gate resistors and possibly the drivers.

They are using FQP65n06's as the fets . I looked up the datasheet for theese and as far as i can tell the rfp70n06's would be a good sub.

In your opinion would theese be a good sub for the power supply fets?

The 70n06 should be a good sub but I'd recommend using the original parts. They are readily available.

Perry,

Do you know what the drivers are for this amp??

They appear to have been messed with at 1 point.

So the drivers that are in it are as followed

Q10P1:A1266

Q11P1:A1266

Q11P:A1266

Q10P:A1266

Q51P:C3198

Q52P:A1266

Q10 and Q11 are the power supply drivers.

Perry,

You said both Q10 and Q11 are the power supply drivers.

Are they both suppose to be A1266's?

Yes.
