Rockville db16 4000/8000? Part substution

I rebuilding a rockville db16 says it's a 4k/8k I'm not sure where those number are fabricated from. It appears to be about a 1500 Watt amp
Anyway the power supply was completely burnt. The transistors in the power supply were 80n08A. Must I use them again or can I use the standard irf3205's in this supply. It has 47R gate resistors already.

The transformer was burnt up as well, had to unwind one wind and cut it and remake some of the smaller windings. It was up and running. Then I went to test the the voltage at the output card the Amp went into protection and won't come out. Anyone know what chip this board runs, or I could use some help, troubleshooting the protection.
Maybe irs2110?
