Alpine mrp-m1000 amp repair question

[woc47 10+ year member]

Hello i am seeking any help with repairing this amp. I'll include pictures. I have some electrical background knowledge. I have repaired 7 amps in the past (was extra cash for college) but haven't done so in about 2 years. I am having trouble identifying this mosfet model so i know which one to buy. Any help would be appreciated thanks.

Note: the two mosfets next to the burnt one is labled Y 744 and Y 734 if that helps. The one that is burnt is not legible does anyone have this amp and maybe could let me know the proper mosfet. Thanks for the help

just a couple tips on pics- first, it helps to use macro so you can take a clear up-close pic. i like to rest my hand or phone/camera on something so it doesn't wiggle/blurr when i hit the button, and 2nd- i wish people would stop using imaqge shack. i guess that's just my preference, but it always opens up adware windows on me and loads other ad malware, then i have to do a clean-up and loose my site cookies/preferences. sorry for the rant- back to the task. what are the other digits before those numbers. i believe the yk734/744 are the build date/line indicators, and the larger digits above are the part number. look for the manufacturer symbol as well. i'm trying to see exactly what those do. rail regulators? drivers? also, check out those caps. might be the pic, but they don't look good.

How did this amp get damaged?

Curious because I have a MRP M500.
