Bose Acoustimass 10 IV Subwoofer No Sound. Help with burnt component identification?

[St66666]

MJH6287 / 84 seem a proper match, stock at digikey. the board is a single channel classH amplifier with 20V and 40V rails. the diodes look like 100V 20A types, not sure whether schottky or normal diodes, measure the forward voltage of the good one. this schematic seems to fit the board in the picture.

Do you have by any chance a page where the LM339 chips are shown? It's beside C25 in the middle of the board. I have electrolyte leak there and it destroyed some traces and smd parts.
