Parasound PLD2000 preamp problem

Does anyone know where to find obsolete parts, such as the balance pot on this preamp? Having issues with lost right channel and scratchiness in balance pot. Cannot restore right channel after multiple cleanings with deoxit. I think the pot is junk, feels very rough and center detent is a bit out of whack, if that makes any sense. It seems as though there are several "detents". Not sure what that means. Is it possible to match it up with a different pot as this one seems to be obsolete. I have searched everywhere and cannot find an exact match. It may be an Alps piece but not sure and if so, they don't seem to make it anymore. Any help would be appreciated. Thanks,
Bill

The footprint does seem to be standard, 12 pin. I found one that I thought was correct but it turned out to be a volume pot. This came from Ali Express, kind of difficult to navigate, seems to ignore pertinent data. I will try Parts Connexion? Correct spelling? Thanks,
