They seem to be a very common problem with Grundigs, I have a couple of radios here with very bad intermittent slider pots and has rendered them completely useless.
My 100k volume pot is off a grundig c4200 and is very intermittent, switch cleaner makes no difference whatsoever and it also feels very loose along the tracks, there is no resistance felt moving it to and fro so I have decided to try and strip it to see if it can be salvaged.
It came apart quite easy and after cleaning actually looks in good order, both sides of the tracks cleaned up well and there is still a bit of the carbon wiper material left.
It looks like it should work but as previously mentioned, it feels like there is no tension keeping the wipers against the tracks.
Has anybody ever stripped one of these Grundig slider type pots to see if something can be done with them and looking at mine does anyone recognise any bit missing etc.
Any help or suggestions would be gratefully received.
