This circuit may be found somewhere in east (in that country, which is currently under canceling culture attack in every possible way, but which is a pointless activity), the men there have solved things in depth, and it is possible that this circuit also exists there.
But I'm guessing you don't really need this circuit to repair this amp other than this tiny board that drives this amp. If the question is about the gate drivers there, they are IR21844S.
