I do have the resistor Mr Babin, but it’s discolored I could presumed it’s a low ohm as there’s silver band before the last band which is brown but the R97 seems 5.6ish (6ohms on my fluke) however when I measure it as it is it’s giving me 15ohms reading, that’s what I can’t ascertain if both are same, I’ll look on the layout and see if it designed as your schematic today. (And I was trying to work from atop the amps I didn’t pull the board out of chassis yet). Any comment on the output mosfets? I’ve ask knowing two is damaged, should I replace two or all six for the bank?
There are two banks per driver IC. It appears that one in each bank failed so you need to replace all 6.
After replacing the resistor, you can test the IC with the 4 remaining ICs to see if the driver IC survived.
That's what I see. 5.6 ohms.

I’ve test it (from top) and all indication proves it’s in liking of the diagram you sent, does that concludes that both should be 5.6ohms?
Why haven't you taken it out of the heatsink? You can't replace it from the top and confirm that you have a good connection on the bottom of the board.
I think they should be the same if they're connected like the resistors in the diagram.
