Hopefully we can help eachother out. I have the same amp here Mines missing the fets and rectifiers.

The resistors that yours is missing are:

R109,R108,R107 They are:33 ohm

R101,R102,R103 They are:22ohm

Wondering if you could tell me what fets are in this amp and whats in locations DH1,DH2,DH3,DH4

the outputs 1-4 use 9640's and. 7-9 the other use 19n20's.
and the power supply in this amp use irfz44's.
