I’ve been in need of an outlet to break up the days of working on startups and programming. As such, I’ve taken up the hobby of restoring vintage Bang and Olufsen stereos. It actually started out of necessity since one of my B&O stereos broke. Instead of sending it in for repair, I took it apart and fixed it. So began my latest hobby.
I’ve always loved the Beovox 4500 and Beolab 4500 speakers. They are one of the finest minimal designs which remind me of the paintings of Piet Mondrian. I found a pair in need of some serious restoration. Here are some pictures from the restoration project.
Here is a picture of one prior to restoration:

Eric, great looking job. I have a vintage B&O unit as well. The main restoration needed in replacing the stainless steel trim. Where did you fine the right thickness s.s. and get it cut to size? Thank you!
It’s a bit hard to find the exact thickness. Most shops carry stainless that is a little thicker. In my opinion, that’s a good thing since it’s more dent resistant now. However, the thicker metal is harder to get a crisp bend to. So expect a bit more of a rounded bend, not the crisp line that B&O achieved.
You can get it cut and bent at any metal fabrication shop. Most cities have one or two. I’m working with a local shop that does lots of stainless countertops, duct work, etc. They squeeze in my little jobs when they have extra time. If you do go to one, it’s best to bring the original sample pulled from the device. While you can give them a diagram, measurements might change if the metal thickness changes. It’s easiest to just have them match the inner dimensions of the sample. Obviously, you want the piece to reattach in the same manner.
It’s quite a project, but anything vintage usually is. Keep checking back for a major Penta speaker restoration I’m working on.
Thanks for the reply. Fortunately for me, the Penta’s look great. It is just the cd player that has gotten a bit scratched and dinged over the year.

I was curious whether you were able to get a truly straight line on the bends. The local shops I used have hydraulic break presses, and they used this to put the bends in. The bends though were generally straight, but had some waves in the crease. Not good. Did you get good results like the factory pieces? What did you use to get those results, if you got good bends?
John, The stainless for these had some minor waviness from the same type of break. However, another batch of metal for a Penta restoration didn’t have any waviness. As such, I think the straightness from this type of break is inconsistent. To see how well the Penta metal came out, see this thread at the Beoworld forums:

I believe you can achieve a very straight line by scoring the rear of the panel before it is bent/pressed.
Does anyone know where to get a similar cloth for the frets?
LG,
This cloth was purchased from http://www.parts-express.com/ but you might also try a clothing fabric store. Hope that helps.
Cheers,

I have a pair of B&O speakers similar to those above but they are 33.5 inches tall and 18 inches wide. I want to sell them along with the Beosystem 4500 Receiver, CD, Cassette, and remote.
My problem is I don’t know what and can’t find the model number of the speakers – would you have any idea. I bought the system in 1989, it is in great shape just don’t have the space for it anymore.
Please let me know
Thanks
Althea,
Sounds like Beolab 5000′s. Check out this page: http://www.beoworld.org/prod_details.asp?pid=369 You can also email me from my contact page and perhaps I can give you a hand.
Cheers,
Eric
