    Default Crackle on balance centre knob... Help???

    Apologies, but I am unrepentantly looking for some thoughts from the wise hifi viziers on this forum...

    My Pioneer SA-5000 has distortion and crackle only on the centrepoint of its balance knob. Obviously where I usually plonk it!?

    Is this a biggy? I love my hifi, vinyl, and music but as they say up here in the North “I divn’t naah owt...” about the technical goings on inside the machinery.. 😮

    Any ideas/thoughts gratefully received.

    It's probably a bit of dirt on the track inside the control potentiometer. If it was me, I'd buy a decent quality switch cleaner aerosol and give it a squirt from inside the case, then work the control back and forth a few times. That may sort it.

    Definitely try the contact cleaner before considering anything more drastic.
    I recently sorted the controls on a mates Rotel amp from the late 70's.
    I thought the crackly Volume control might be knackered, but a few squirts of said cleaner had it working smooth and silent.
    Had the can a while, got it from Maplins, but that door just closed.
    Probably get some off the web.

    Deoxit D5 is the best cleaner Lube ive used, its not cheap but works very well and is a long lasting fix
