Sorry, but I do not know if it will or not ....

Its got to be close enough, thank you very much!!
This amp was stripped and used for parts and I am trying to revive it it.
So far everything is a go but I have one issue.
Q123 and Q110 read OL from gate to source testing with my meter.
Various components were missing and I have replaced alot of SMD components. These are the only two output fets that read this, the rest check out fine.
There must be something open or faulty somewhere just not sure where to look.
Hoping someone can steer me in the right direction.

Maybe, I'm not best placed to help you, but I can give you some idea as to help you ..
Q110 and Q123 If (IRF540) you get 0 on the meter, must be short, and you have to replace them.
You should also review, Q121, Q122, and D106, for just in case, they were wrong, or leaking, (is what I would do ...)
I repaired a, 700S and 851X, which are very similar to that you have.

Yes thanks for the advice but all those have been changed because they were missing. Every smd diode and transistor in that area is brand new along with all of the outputs. I must have an open or out of tolerance resistor somewhere to get the 36 vdc on the left front bridging terminal.
Not really sure where else to look??

So .... Have you Q110 and Q123 is also changed? and do you still gives 0 on the meter, after being replaced?
That's odd ..
If these transistors are short, it is normal to have 36v at the output of audio ...
There must be wrong, something more ..
I do not think that tolerance of the resistors is the cause of this failure.
Do not know what else to tell you, sorry.

From the gate of Q110 to the emitter of Q121 is 40.1 ohms
From the gate of Q110 to the emitter of Q122 is 40.1 ohms
They are both the same.
One thing to mention its hard to tell because they are so close together but Q100-Q104 all or some of them are getting VERY hot.
Thoughts?
