  I bought this 4b back in 86. It recently blew one channel, and every time i replace the fuse it blows again. Unfortunately it took out a midrange driver in my N802's.
 Not being familiar with the real differences between the original 4b, and the subsequent other models, ST, SST (any others?), do i get this repaired? If so, do I send it back to Bryston, or would it matter if I took it to a local repair shop?
 At the time that I bought it Bryston was not offering the 20 year warranty that they are known for now, but that fact tells me it should be good for many more years than the 22 yo it has logged so far.
 I am of modest means so unlimited funds to buy new is not gonna happen unless this amp is toast.
 Are there any audible sonic differences between the different models?
thanks for any help

I would recommend contacting Bryston about a repair.  If a repair is not possible I would also check audiogon for used Bryston equipment.  I recently saw a Bryston 4B for sale for $445.  Typically a used 4B-ST goes for around $1200 and a used 4B-SST goes for around $2200.  People claim there are differences between the series, but I am not familiar with the details.  However, I do know that Bryston made substaintial improvements in the power supply (larger transformers and capacitors) when going from the 4B-ST to 4B-SST. 

Lastly, I own a 4B-SST.

Good luck and let me know how things turn out.

Cheers,

John

 If you look at the cost of sending it back for service , the cost of service etc. you are  left with an amp perhaps best not repaired.

Newer Bryston amps are very significantly better ( I've owned both ST and SST series-with the SST being the biggest jump).

If you can afford a used SST , then that is a great option but something like a new NAD C272 150x2 power amp at approx. $800 ( before a discount ) would give a more modern sound for less money .

Everyone make great points. Contact Bryston and perhaps get a quote of some kind if possible. Used 4b's can be had for 500-700 dollars that can still have a few years warranty left on them.  As far as AMP technology I would think the technology has not changed a whole lot. Still, I am sure the Bryston amps have only improved over the years.  To add, I have owned a few NAD C272, and have one here at the house right now. Sonically, it is nowhere close to my 16 year old Minty Bryston 3b. The 3B smashes it in the sound quality department in my opinion. Don't get me wrong the C272 is one of the better amps you can buy under 1000. However, Bryston is still Bryston no matter how old it is. They are built to last forever, and have always been top of their class in sound IMO. Used Bryston stuff right now is an amazing investment as it can be had for a good price, with warranty left on it. And if you decide to sell, you will rarely lose money on it. Contact your local dealers to see if they have anything in stock. But first, contact Bryston about the 4b. Cheers.

I would contact Bryston and consider having it upgraded to SST status. I am sure it will cost less than buying a new 4BSST. I would also keep the old chassis, if possible! Much like new wine in old bottles! That will give you another 20 years warranty that will surely last the next generation!

Best regards

I don't believe they're upgradable. But Bryston has a truly excellent and well earned reputation for customer service. i had heard that at one time their unwritten policy used to be -- if it says Bryston on it and it's broke, we'll fix it -- no 20 yr limit -- those days may be past but I would not be at all surprised if they didn't charge you very much at all to fix it. They are really nice and very professional -- contact them and see what they say.

I am only 26 years of age, and am fairly new in the hobby, and am still learning. So , I called Bryston a few times, talking to them is fantastic. They talk to you like a human, and give it to you straight up, in a polite manner.  There is, I believe a 75 bench fee and then they call to you let you know what is wrong with it. I can almost guarantee that it will be much cheaper to fix the 4b then to buy a new amp. But hey, its your money, I don't want to spend it for you.lol.  The original 4b's NRB/Legacy series are not upgradable to the SST. Even if I were to go buy a new SST amp, personally, I would probably still fix the 4b. You just can't have a broken 4B laying around. Cheers.

I'm going against by peers a bit here but I usually take my stuff to a local repair person.  Ask around for someone in your area who does good work.  If it is something simple it might cost 1-2 hours labor plus parts.  If it is more complex and expensive your out only an hour or so of labor.  If you sent it to Bryston, you'd pay $75 at least plus shipping (that amp is heavy!).  So, if you're looking for the cheapest repair (it sounds like this is the case) go with good local.  If you want it repaired by a person most familiar with that model send it to Bryston but be prepared to (possibly) pay more for the repair.

Good luck!

Yeah, but cheapest can end up being the most expensive in the long run. Sending it to Bryston is the best option.
