Thanks all. Heat is an issue and I am experimenting w amps outside the cabinet. Interestingly, the 150s and one of the ref 600 m amps have been fine in the cabinet the entire time.
So I have to think at least one of the ref 600 is defective as it emits sound only around 30 percent of the time. I am disappointed bel canto has not offered to refurbish or swap the amp, they just deny the problem.
