3B-ST Making Strange Noise
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 797 Registered: Jun-08 | O.k. guys, I know I've mentioned a number of times and quite recently that my Brystom 3B-ST has a mechanical hum that seems a touch louder than the norm but now there's a new noise, which seems to be a symptom of something more serious. When I shut the amp of, right after the lights go out I hear this creak from the inside towards the back. It actually sounds like a creaking door or the sound of a fan on a computer that's had a bit too much mileage. I know the 3B doesn't have a fan so what could be causing the creak, which happens consistently when its shut down. This happens whether the pre is on or off and whether a source is on or off...no noise on the speakers though. It also appears to be a mechanical creak. I'm thinking the power supplies are the culprits and in need of tune up or replacement. More reason, justification, to send it back to Bryston. |

Gold Member Username: Nickelbut10Post Number: 2551 Registered: Jun-07 | George, does the noise come from the speaker or from inside the actual amp? email Mike Pickett. mpickett@bryston.com He will have answer back to you promptly. |

Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 798 Registered: Jun-08 | Noise is from the amp itself only when it shuts down a few seconds after the power lights go out you hear a creak, which is fairly loud. It can be heard from 8ft away in a quiet room, easily. I thought it was the fan in my Rogers HD-PVR 8300 but no, it wasn't, it was the 3B-ST. I'm in the middle of my move but yes, I'll need to call Bryston next week. The big problem is I don't have a Bryston box to ship it in and my need to get them to send me one...I believe they can cost around $40 to $50. |

They're definitely a world class company when it comes to this stuff. Bryston gear doesn't cost a lot and retain its value for no reason at all. |

I wouldn't think the Bryston amplifier would use mechanical relays anywhere in their product but that would be the sound you might expect from a relay that is sticking/failing. I would expect it has to do with some sort of muting circuit Bryston is using - in place of old fashioned relays - to disconnect the output of the transistors from the speakers. This is possibly done to prevent any DC volatge from leaking through to the speakers as circuits shut down. The Bryston is a direct coupled amplifier - no output transformers - and the designers might feel frequency response down to (near) DC is a good thing as long as the amp is working as planned. If this is even remotely the case, you need to contact Bryston immediately since it only takes one brief meeting of woofer and DCV to end the woofer's life. . |

Gold Member Username: Nickelbut10Post Number: 2552 Registered: Jun-07 | Jan is on to something. Their Legacy stuff use to use the old fashioned replays so when you turned the power amp off you would hear a CHIRP CHIRP coming from the relay's. I guess it could be described as a creeking noise. They use a muting circuit now to make the noise go away and protect the speaker better. I was told this by Brian Russel at Bryston. My amp use to make the chirp sound, when I got it back from Bryston, it doesn't anymore. George- I personally couldn't wait for next week to call. Email them. They will have a reply back in less than a couple hours. Or call, the guys will tell you what it is right over the phone. |

Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 799 Registered: Jun-08 | Yeah Nick, I'm sure but besides having a couple secs to check email I've got no time. Packing and unpacking boxes and runs from my current house to the temporary digs...wanna come help with the move..LOL. The Bryston is packed now in a box to take over to the new digs so it's not going to be running until I drop them an email / make a phone call, which I'll try to do this week, if not next. Thanks for giving me some insight on this Jan and Nick. I'll mention it to them, as well. Cheers, G |

Gold Member Username: StryvnWisconsin Post Number: 1139 Registered: Dec-06 | In that case, I think it's obviously the Bryston cellar door closing after the power has been switched off. |
|
Gold Member Username: Nickelbut10Post Number: 2553 Registered: Jun-07 | lol George- I had no idea you were moving. Packing sucks. Unpacking in the new digs is fun. lol I wish you good weather. |
|
Platinum Member Username: NuckPost Number: 12530 Registered: Dec-04 | Nick has a shipping box to lend you George. Right Nick? |
|
Gold Member Username: Nickelbut10Post Number: 2555 Registered: Jun-07 | Yup, I do. They gave me a new one for the .5b as well. Both boxes were 35 dollars. George, when you contact them, as if any 3B box will work? |
|
Gold Member Username: Nickelbut10Post Number: 2556 Registered: Jun-07 | Oh, and you pay for the specially made inserts. Thats why it cost 35 dollars.lol. |
|
Platinum Member Username: NuckPost Number: 12536 Registered: Dec-04 | Who pays for the empty box to get to you? |
|
Gold Member Username: Nickelbut10Post Number: 2558 Registered: Jun-07 | You can ship it anyway you like to get to Bryston. But once the repair is done, they will not ship it back in anything but the dedicated Bryston box. I had my shipping department at work ship the 3B, it was shipped like glass. We ship about 10-15 large Rackmoutable 60-100 pound DVR's a day, so I wasn't worried. They didn't care, they wanted me to buy the box.lol. But hey, it covers your butt as much as it does theirs. With a warranty service like they have, I would want to make sure it got back to the customer properly as well. |

Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2621 Registered: Feb-07 | That's interesting that you mention the "chirp" sound. My ancient 3B does that too. Maybe a day trip to Peterborough is in order George. |
|
Platinum Member Username: NuckPost Number: 12543 Registered: Dec-04 | Field trip!!! |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2624 Registered: Feb-07 | Too bad I didn't still have my mini-van. |
|
Gold Member Username: Nickelbut10Post Number: 2559 Registered: Jun-07 | We can take my Civic.lol. Cram in there boys. The Legacy puppies were meant to chirp. Thats how they roll.lol. You think Bryston will let us into their factory. I am definitely wearing a black ski mask and coming out of there with at least 3 x 28bsst's. Dave you get one side, I will get the other with George and Nuck.LOL!!! |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2631 Registered: Feb-07 | I'm not sure they'll let you in wearing a black ski mask, but count me in! |
|
Gold Member Username: ArtkAlbany, Oregon USA Post Number: 9760 Registered: Feb-05 | Make it 4 and I'll give ya some black market bucks and meet ya at the border. |

Platinum Member Username: NuckPost Number: 12547 Registered: Dec-04 | Used, non sequential bills of small denomination... |
|
Platinum Member Username: NuckPost Number: 12548 Registered: Dec-04 | All in Nick's gym bag, so as to deter the border idiots from looking. |
|
Gold Member Username: ArtkAlbany, Oregon USA Post Number: 9763 Registered: Feb-05 | Absolutely Nuck...I know the drill...lol! |
|
Gold Member Username: Nickelbut10Post Number: 2560 Registered: Jun-07 | LOL!!!! Nice. |
|
Platinum Member Username: NuckPost Number: 12552 Registered: Dec-04 | Hey, it was free. I am in for the tour guys. Who is gonna QB this one? I think Nick has the best 'in' to find out when. If a whole weekend can be had, i say we go to Axiom as well, I have hotel rooms for all involved. |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2633 Registered: Feb-07 | Just give me sufficient time to "run it by" the powers that be. |
|
Platinum Member Username: NuckPost Number: 12553 Registered: Dec-04 | Rooms to spare, bring the gang, Mom and kids can shop while we tour. Saturday night drunken disaster in need of supervision. |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2634 Registered: Feb-07 | lol... sounds like a good time actually. |
|
Platinum Member Username: NuckPost Number: 12554 Registered: Dec-04 | It might just work. George, are you listening? |
|
Gold Member Username: Nickelbut10Post Number: 2561 Registered: Jun-07 | LOL I am game. Like David, give me a few weeks notice. It does sound like a blast. |
|
Platinum Member Username: NuckPost Number: 12555 Registered: Dec-04 | OK Nick, you are the QB, cause I am on the move. Call and find out the sched, mano. |

Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 800 Registered: Jun-08 | O.k. I just got back to work and check this thread and you guys have been making some plans I see. I'll need to dig out my mask. Personally, I had thought about doing a trip to old Peterborough to drop of my puppy in person. If things are alligned, I'd love to do a tour of Bryston. My 3B-ST is packed in a Samsung 26" monitor box right now in storage. We did the big move the past few days, no time to check emails or forums etc. I'm just starting to get back into the groove but boy am I tired. I don't want to think about doing this again in Jan/Feb when the new house is built but we'll have more energy knowing were settling in for the long term. Keep me in the loop on any plans. Cheers, G |

Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2648 Registered: Feb-07 | Moving sucks George. I guess you won't be enjoying your system till you get in the new house... are you gonna have your own listening room in the new digs? |
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 801 Registered: Jun-08 | Yeah Dave, but it will be in the unfinished basement, until it gets finished, which won't be for a few years. I may put up some temporary walls to close it in and get some of those hard rubberized shop floor foam tiles, which should deal with the reflection. I have access to my Dad's Energy Pro22 Reference Monitors now, which were the CBC's reference monitors in the 80's. They have a wonderful midrange on them with a warm sound. Comparative to the Staff sound, though without the same resolution. I've got my PS3 hooked up and need to get my TT going, so there will be music but not as much since the whole family is sharing one open space...basement loft style, I guess. |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2654 Registered: Feb-07 | As a temporary measure for your new basement (when you move in) you could use these interlocking foam tiles from Crappy Tire. I used them in my basement. They're cheaper than the rubberized shop floor tiles, softer, and they don't have that gross rubber smell. |

Platinum Member Username: NuckPost Number: 12608 Registered: Dec-04 | Rubbers only smell gross after use... |

Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2656 Registered: Feb-07 | Nuck Nuck, Nuck.... |

Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2658 Registered: Feb-07 | We used to call them "Lake Ontario Whitefish". |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2659 Registered: Feb-07 | Man, how do we get so far off topic? |
|
Gold Member Username: My_rantzAustralia Post Number: 2233 Registered: Nov-05 | Kids, go to your room quick, Uncle Nuck is here!  |
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 802 Registered: Jun-08 | Whoa, boys and their imaginations...LOL. Thanks for the tip Dave...the posession date is still about 7 to 8 months away but it's nice to think about it. I'm really excited about seeing this house get built in the meantime. |
|
Gold Member Username: DmitchellOttawa, Ontario Canada Post Number: 2661 Registered: Feb-07 | No problem George. |
|
Platinum Member Username: NuckPost Number: 12616 Registered: Dec-04 | Tell us about your listening room in the new place being built,George. |
|
Silver Member Username: SoundgameRichmond Hill Toronto, Ontario Canada Post Number: 803 Registered: Jun-08 | The room will be in the basement but I haven't yet worked on a plan. Eventally the basement will house a dedicated home theatre room, a listening/reading room and an open recreation area. The office is on the main floor and the laundry is upstairs so they won't take any room in the basement. So other than the washroom the basement will have three rooms. I haven't set pen to paper to plan how the basement will be best divided to accomplish this but I do know there should be sufficient room. Ultimately, I'm not after setting up a huge room but it looks like it will be about 12' X 15 '. I'll sound insulate the walls and ceiling, have a dedicated power supply, most likely a separate breaker box and will use wall treatments. All things in time though, the house is got to get built first, we'll need to decorate and landscape and then I'll look into plans for the basement. In the meantime the home theatre will be upstairs and I'll carve out a space for my listening room in the unfinished basement...temporary walls, possibly the separate power supply and the foam tile floor. Not sure what I'll do with the ceiling, maybe some drywall there too, temporarilty. |
