Each Bryston hand built: is each item built by one person? or an assembly line?

James:
When I got my Bryston BP 1.5 my understanding is ONE person built it from scratch.(I don't know if the 4B-SST2 and BP-26 and power supply also get this attention?)
Are the amps etc all built this way? Or do some people put together parts and then another person adds some others?
I would think some folks specialize in usually building a few kinds of product? Or do all the workers just build the next item needed? (i would think the finest amps, like the 28B-SST2 have specialized workers?)
Just curiousity from a thread about hand built in general on another site, and I wanted to brag my Bryston is hand built!! But i wanted to get my facts straight beforehand.
Thanks. (I LIKE to brag about my Bryston stuff!!, and I have had personal emails asking why the BP-26 and why it is my choice over other preamps... I have to say it just sounds better!)

Hi Elizabeth,

Generally there are specialized people at specfic areas in the plant - so we have a preamp section and a power amp section for instance.  Within that section all things to do with that specfic product are manufactured by people who just do preamps etc.  Some people are crossed trained to move to a different area of course in case of high demand on a specfic product, holidays, sickness etc.

Yes everything is hand built or assembled from the basic parts and each and every one of the units are tested a number of times during the assembly process. For instance, the individual parts are tested before they go into a circuit board (caps, transistors, etc.) - then the finished board is tested - then the product is tested again with the circuit board installed.

Each and every piece of gear then undergoes a rigorous 4 day 'burn-in'. The amps for instance we cycle one hour on - one hour off at full output into a capacitive load to stress the components - usually a component will fail during this test rather than in the field.  If the part fails then the product has to
go through the complete test again with the new part installed.

After the burn in is passed then a specialized technician(s) in each area do the final checkout on a computer test gig and make sure all the measurments are within spec. They write up the customers test sheet (and a copy for us) and finally hand tune if something is not quite right and do a final cosmetic check-over.

So.. does one person build an item from start to finish?
Then another person may do the testing etc.
Just wondered.
I mean i can see one person doing a circuit board, then another assembling some parts then a third doing the final assembly. but i just wondered is some things like the phono get done by a single person buildin it?

No - someone that is expert at fine details, like circuit board assembly, may not be good at lifting 40 pound transformers. :D

Yeah, i would be hard pressed to be lifting 28BSST2...

Thanks.

It gives me a warm and fuzzy feeling deep down knowing my Beasties were not assembled this way....

James,

are there specific things during the process of building a device that is only done by women/man? does Bryston follows the skill of their employees?

al.

...and how many male/female are working at Bryston?

Not everybody gets to build the 28's. Here is some sneak footage of Bryston's HR department going through the applicants as to who will be trained.

Seriously?

Because a programmed SMT machine is going to give you a 100% accurate job of placing components compared to hoping that a person has remembered how to place everything.  I can't think of a more boring job than placing components.

My '30 years on the job' job was often boring to other folks, but i found i loved it. Some folks find doing a task very rewarding. It is all in how one thinks about it.
Sometime I would fantasize "I am a robot"....If the task was particularly repetitive...  fun, yes.
The best part is i can do anything no matter how monotonous, now. (If i feel like it)
Where way too many people now can only do something for five seconds and give up. (Like looking through thousands of used CDs in the discount shelving at a local store. I go about once a month so the stock has changed enough to make it worthwhile, I can sit and look through every single one, a handful at a time. 3 hours straight no problem. The rewards are i find all sorts of great stuff. I have NEVER seen another person be able to look for more than five minutes before they give up.
Maybe i should get a job at Bryston?
I actually have pride in what i do when working and that is the number one job skill i would think they want! My second is doing it right or not doing it at all!
PS Jim Tanner: No way am I gonna get off my (now) fat arse to work, what with a great pension (our plan belongs to us workers, and has 5 Billion$$$ in it..).. and Social Security coming in a few more months.. I'll be raking in more than I did when i actually had a job.!!!
And i bought my Bryston stuff with the retirement bonus they suckered me out the door with..

Never thought about it but I would guess we have as many men as women working with us at Bryston.

Machines are fine and we use them in many areas where it makes sense to do so.  There is nothing wrong with insertion machines and some of our newer products use that technique in specfic areas on the circuit boards and in other areas we use hand insertion - ex is the DAC and the BDP-1.

It's the checking and testing to make sure they work as they should that is important.

+1 ! The end result speaks for itself and I am enjoying it to the utmost as I type this reply. James : Where's my BHA ?

Hi D.D.

Working hard on it - based on initial testing I think we will go the Discrete Circuit route.
