I have one of these newer amps.

Totally dead to the world. all mosfets are good. no bad ouputs, no bad powersupply.

I had noticed an ISP header, and was like huh....

pulled it apart, it uses a ATTiny13V in what appears to be the turn-on/regulator circuit.

Well, the 5V is about 0.585v.

the other side of the 5V regulator U3 is about 1V. Not good.

Q1 appears open B to E, anyone have any more info on this amp, or what this transistor actually is? all i have is a 2GM marking with a sideways B.
