I experienced the same thing with a Bryston 14bsst amp. One channel would go rogue and get extremely hot, then the warning light would come on and shut down the amp. Sent it to Bryston repair and they said it was a bad bias and ended up replacing the entire left channel mother board (whatever that means!). It has worked perfectly since.
Classe CA-2100 - LED turn red, Amp shuts down, LEFT side of the Amp is extremely hot!
My Amp, which is a Classe CA-2100, has been acting up. It has a status LED light in front that usually stays Blue, but lately, the left channel LED turns RED and it shuts down. Whenever that happens when I goto the Chassis, the LEFT SIDE is extremely HOT! Like super hot to touch. NOT the right side.
The company is in restructuring so I am trying to see if I could get any support, but being a computer engineer and knowing a few things about electronics, is there a way for me to test and see what component is failing? I have access to multi-meter to do some measurements if necessary.
