Bryston 4B gets HOT. Should I leave it on?


My 4B is 25 years old and gets smoking hot. I sherk my hand when I touch it. Is this seem normal for an old amplifier? It's off the ground and I'm going to add a fan near it to help ventilate...

My entire room gets warm because of it! I would rather turn it off when not in use to 1) save power and 2) reduce the heat buidup. However, I've been told that leaving it on is both better SOUNDING and EASIER on the components (less wear and tear). What do you guys think? Can I turn this oven off?

Bryston's are not biased high enough to get this hot during normal operation or at idle. As such, your amp is in need of attention. I would contact Bryston USA and send it in for service. While your unit is no longer under warranty, Bryston is phenomenally good about standing behind their products and doing so at very reasonable rates. Sean

Sean's advice is on the mark. A good friend has the same model Bryston amp as yours (he's using his in a second system), and his amp never gets terribly hot, even when being driven hard. While it may be easier on the internal components of solid state amps to leave them turned on, it is NOT good for those components to be continually exposed to high heat levels at idle.

You could send your amp immediately to the Bryston repair facility in Vermont, but you might first seek the advice of James Tanner, the technical expert at Bryston. You can send an E-mail to Tanner by going to Bryston's home web page, and clicking on the link at the bottom that reads "Technical questions please click here". On business days, Tanner normally responds to questions within 3-4 hours.

Until you get your amp checked, I'd recommend turning it off when not in use. When you plan to use it, turn the amp on about 20 minutes or so before playing music.
I feel like since I cannot afford to send it back right now, that I should turn it off and on until one day it breaks. Then, since Bryston charges fair repair costs, I'll send it back...?
Yes, you could wait until the amp quits working to send it in for repair, but by then you may face a much more expensive process due to deterioration or failure of other internal components. Like the Fram air filter ad used to say: you can pay me now (probably cheaper), or you can pay me later (almost certainly to be more expensive after a major problem). I'd send an E-mail to James Tanner and ask his advice -- that costs nothing, and may yield some very useful information.
I, too, owned the 4B for 10 years. Heat 'twas never a problem. Good advice above. peace, warren
