Technics SU-MA10 volume control bad

[Technics-goy]

Hi,

I am having a problem with two of mine SU-MA10, the volume control is getting bad on both, it's really annoying. I realize these are 4 gang pot's, 2x 100k log + 2x 50k log, I assume. Something really special, I guess.

So what are the chances to find a replacement ?

Are there any mods for this amp ?

Cheers

Are they scratchy? If so, they just need a good cleaning with Deox and Faderlube.

Hi Cademan, thanks for offering me help. I had already tried the cleaning but no joy. It seems the pots have worn off the resistive/conductive material in some spots. I need some replacement parts I guess.
Any pointers if they can still be found somewhere ?
