Potentiometer repair kit



You are looking at a repair set for the sliding potentiometers used for the tonecontrols in some of the classic 1970s Bang & Olufsen design stereo receivers.

The problem with the original part is that the sliding part of the potentiometer breaks, causing the little bronze sliders underneath to lose contact.
This again causes dropouts or completely silent channels, sluggish, intermittent or completely non-working tonecontrols etc.
The problem affects the bass, treble and balance sliders in

Beomaster 1900
Beomaster 1900-2
Beomaster 2300
Beomaster 2400
Beomaster 2400-2

The potentiometers were custom produced for B&O and replacement parts has been unavailable for ages.
A new type of replacement potentiometers were available from B&O at some point but it was only for a very short period of time and only very few receivers, mainly the later models Beomaster 2200 and 2400-2 got them.

This kit is for the old type potentiometers RUWIDO PSK 13.359.00 (the ones that break).
It contains the three pieces needed to repair the bass, treble and balance control sliders.

The new parts have been improved over the originals in that the material has been made practically unbreakable and the problem areas were made stronger, all to prevent future problems.

Instructions can be downloaded in pdf-format using link(s) provided in the order confirmation email.
Basic electronic skills and tools (a little soldering) is required to replace the parts.
You will replace only the broken plastic parts.
You will transfer the little bronze contacts to the new parts and you will reuse the rest of the original potentiometers.

Set of 3 pcs.
