i got this amp from a shop its in bad shape. it has no gate resistors or resistors on the output gate. any help?

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

Ok sorry to ask but do you know what goes in theese locations also: I believe they are the power supply drivers

Q5,Q10,Q6,Q9

And do you know what fets they are using?

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.
