i just bought a used crown 2502 amp. they are on back order for at least a year so ebay is where i got it. it was working before shipping. durring shipping it was thrown and the heatsink tore the fets from the board. also damaged SMD components as it bounced around. package was not insured.
the fets are nvm21 b30h100g. i cant find this exact fet refrence anywhere. closest i can find is

but i dont know if this is right. attached are photos of the fet and its reading. can someone check this. thanks.
given its shipping damage, im assuming after repair it should work.

The silkscreen printing on the pcb of the component in the photo says D108, in fact it is not a mosfet but a
double diode 30A 100V

thank you for verifying. ill order up enough to replace both channels as ill be bridging them. amps are SO HARD to come by these days, decided to try my hand at fixing this one rather than returning the ebay sale.
