Yes they are thankyou so much. Thought it may have been a 2x but U just never know.
If the mosefts still get hot after this what else should U check. I've checked most the resistors around the output area. Diodes. Capacitors. Replaced gate resistors.
Drive board checks out fine and has a nice square wave comming out the 2 pins on the left side if U have the pots and RCA block facing U.

I'll do that now. But in regards to these amps. I assume from the wave I'm seeing one side of the board is high and one side is low correct?
This amp likely has a protection circuit that protects when the circuit doesn't see rail voltage.
Do you see a group of transistors designated as Q85, 86 and 87?

Removed 87 and still in protect however 3 seconds after power up it drops my power supply to 11v which means epic current is being drawn. Similar to when I had a blown output fet. (No outputs are currently shorted
Yes.
Confirm that the rail caps are completely discharged.
Connect the load across the speaker terminals again.
