I got the similar amp. The zener voltage when measured was 5.7v.
I changed the bad diodes and removed the output mosfets. When I turned on the amp the d1 and d5 short. D5 is 15v zener. Without out driverboard it produces all the voltages and dont go into protect. Those two u2 and u3 IC I have doubt on.

I can't read the marking clearly. This is what was used in a similar memphis amp.

Thank you very much. This is the correct part. But I am unable to find these to buy. They are obsolete. Is there anything I can use or try?

The drivers aren't likely to see more than about 20v. You can measure the voltage when testing to confirm.
