one of the A1266 is dead...
The switching I saw on the mosfets must have been from the other transistor (dont have a dual trace scope)

Replaced both A1266's with BC640's.
Now, the amp appears to properly power up, and I get +-52volt rails (with less than 12volts input) but the BC640 thats fitted to the location where the original bad part was, gets very hot, very quickly...
The other BC640 is fairly cool...
Hmm...
