I had to do the same with my BeoMaster 4000 (my 4400 was fine). You'll have a heart attack when you first open the unit, but it's not as scary as it seems! Worth it in the end though, as you'll have one of the best amps B&O have made

Yes, the potentiometers are coal based and could be worn but in most cases it's just dust and dirt on the coal tracks and adjacent contact tracks. Coal tracks are treated with contact cleaner, leave it to soak for a couple of minutes and then wipe dry using cotton buds. The contact tracks needs a good rub with a glasshair brush to make them like new again, they are merely a metal bar. The sliding (bridge) part also needs a gentle cleaning with contact cleaner. Don't leave contact cleaner inside the potentiometer. Dry and clean is good.Originally, the sliders were lubricated using some kind of grease, probably silicone based, you can clean and add new silicon grease if you like (non-hardening type obviously). The potentiometers can be opened fairly easily, comes apart as two plastic shells and a tiny drop of superglue each end of the plastic shells will hold it together again. Furthermore, the holding brackets will also support once mounted.

Hi Dillen,

Thanks a lot for that. It starts cracking while adjusting any of the controls during playback. It is kinda annoying especially when it starts to fade. Aren't these controls carbon coated? Has it got something to do with it wearing off?

Thanks again,

adi.

p.s - i am glad you feel the same about the beomaster 4400

Are they noisy ? That's very common.

Finding replacements is practically impossible so a repair icould be the only way. Take them apart, clean them using contact switch cleaner and a glasshair brush. Watch out for small parts.

The Beomaster 4400 is not old... It's still a young classic.

Hi All,

I am on the lookout for sliding controls (Volume,Treble,Bass etc...) for the BEOMASTER 4400 Type 2417 amp. Apparently my current controls have worn themselves out and i am unable to get replacements for the same [:'(]. I love my B & O (I know its old!). Could someone help me find a replacement?

Thanks.
