Yes, actually the StereoWidthBox MKI worked somehow like that.

One cable to the Beolab 5000 Center speaker output and in the box some heavy resistors, I have not seen any circuit of this one nor have I actually opened one. (Could be done of course 🙂  )

Thanks.

My Beolab 5000 manual mentions a Control Box type 6005.

The "Stereo Bredde Regulator" has 20 Ω 23 W resistors attenuating output more or less. The left channel + goes directly to the negative centre output and the right - output is attenuated and goes to the positive pin.

I don't really understand how the rotactor is cabled to the resistors.

Let's see what can be done...

I've found an elegant way of cabling a seven position two wafer rotary switch, so that it switches resistors and inverts speaker polarities each side of the '0' central position. A lot of head-scratching was involved, in spite of my - rusty - electrician  background 😎

I wonder whether Frede has come up with the same solution!

Hello, today I am very happy to have completed my beolab 5000 system. It now contains the following devices: Beolab 5000(soon finished with new capacitors with invaluable help by Sörens guide), Beomaster 5000, Beogram 3000, Beovox 5000(2), Beovox2500(2). The beocord will maybe be a part but is not something I prioritize at the moment, they are still not too hard to come by. I am very interested in the Stereo Width box, though. If someone is going to produce a more or less exact copy I am in to buy one.

Contact Frede (classic) for your stereo width box.

You have a great system.

Well, if you don't need the headphone output, but only the centre speaker, you could fabricate one as I did. The diagram and details are here on this forum!

But of course, Frede's box is superb and the only logical way to go if you want the real thing.

Seen this one on eBay ?

I asked for the auction. A bit high, and not mint.

well the guy above is selling replica ones for 330 euros so maybe  not? who knows ... hard to value it really

Hi Frede,

How much should I pay for a used stereo width box that I would send to you for restoration? Do you still make replicas of the stereo width box?

Thanks,

Chris Wargny
