ED is the mark. The rest is probably a production code.

Is there a resistor I can remove to disconnect the preamp section from the power amp section on this amp?
R300 should do it but I don't know if it will be stable with it removed.
Why do you want to break the connection between the two sections?

HI perry! it is drawing current and going in to protect all transistors test good and one of the transformers is wining!
How much current is it drawing?
Is there excessive DC on the speaker terminals?
Are any of the FETs getting hot?

Its drawing 25 amps. no dc on speaker terminals. I have not left it on long enough to see if the fets are getting hot.
Do you have a current limiter so that you can check the various drive signals without risk to the power transistors?
If so, start with the power supply FETs and check the drive signal for every power supply FET.
