Rockford Fosgate Prime R500x1D

I just received a prime 500x1d I don't see anything shorted or bad except two diodes on the power supply. It's using the t460 mosfets. Two diodes d16 and d8 are bad. Anyone know the voltage of these two diodes?

D8-D16

Are they in parallel with the 33 ohm resistors making them look defective?

No I pulled perry and tested them. They were cracked. The amp will not power up
It's a voltage ladder amplifier. I don't have a schematic to be able to know which diodes and caps need to be replaced to get it running.
