Beomaster 4000 4400 Beocenter 3500 sliding pointer windows

Limited reproduction.

You are looking at the clear windows used for the sliderule dial type potentiometer controls on some of the classic 1970s Bang & Olufsen Beomaster and Beocenter design stereos.

The original lens parts yellow and/or develop “fog” with age (and nicotine) and they rarely look their best anymore. In some cases they have simply fallen off the slider button and gone missing.
The parts are long out of production and has been unavailable for ages.

Early Beograms had closed disc wheels, later Beograms had wheels with ten holes.
Both original wheels had B&O part# 2804012 despite minor differences.
This new idler wheel replaces both types.

The rubber on the original wheels hardens with age.
Typical symptoms are vibrations and an annoying whirring noise when the Beogram is running and playing.
In severe cases, the hardened wheel will slip on the motor pulley, causing uneven playback with audible wow and/or flutter – or no platter rotation at all.
No chemicals will provide a lasting repair, and grinding the wheel down will not soften the rubber (and the wheel would end up a wrong size).
If the Beogram was out of use for a long time the original wheel will have taken shape from the concentrated and constant pressing against the motor pulley causing uneven running and repeated clonk-clonk-clonk sounds because of the deformation to the rubber.
This deformation will have hardened and settled into the rubber material and it will never fall back to original shape again.

The cure is a new wheel.
