My 4B-ST runs Hot

Mullen, glad to hear you love your Legacy's. My wife and I love ours also. An increadible improvement over the Kappa's. Hoping Argent finds out his problem. I'm starting to upgrade and am considering the same amp he is running. Hey, us Legacy owners are at a minimum around here... keep on enjoying!

Argent, there is something wrong with the amp. It is not your load. It is in need of repair if it gets that hot on one side.

Argent, I had the exact same "problem" with the 4BST as you have: The right side of the amp was damn hot! It was happen a month ago. I called Bryston, they suggest that I should switch the speaker cables. And then I found out that I connected the channel1 with right speaker and channel 2 with left speaker; also with my interconnect as well. But I have used the 4BST like that for almost 2 years with no problem. I thought that maybe the problem now, so I correct the connection: Channel 1 connect to left speak and channel 2 connect to right speak and also changed the interconnect. The funny thing is, after that, the right side become pretty steadily as normal as the left side?! Since then, I don't have the warm problem with the right side of the amp. And I don't have any idea why...?

Nope, my speaker cables and interconnects are hooked up correctly. The only other thing that might be causing this is my pre-amp. For anyone who owns a Conrad-Johnson product, you know that they are not phase inverting. This means that when I send the signal out from the amp to the speakers, the red terminal on the Bryston must correspond to the black terminal on the speaker. But even if I hooked that up wrong, which I did not, I still don't see how that could hurt the amp. Phase inversion really just affects the speaker, I think. Anyone else out there who owns a CJ product want to chime in?

Just got a response from Bryston. They want me to see if I can duplicate the problem after I switch my speakers around. Guess they want to rule out a bad speaker or cable. I'm going to try it again, but I've moved my system to different rooms in my house often enough to have switched the speakers around several times. This heat thing has pretty much been a feature of the amp since I got it. Oh well, I'll keep everyone posted on what happens.
