Parasound New Classic 2100 balance pot

Hi,
I'm in the process of repairing damaged pot from Parasound new classic 2100.
looks like a 50K - MN style taper pot (see attached picture). My problem is that I have not been able find a replacement at for example RS-components.
Anybody know the source of a good quality replacement? What would part number for e.g. Bourns, Vishay or ALPS replacement be?

PS: Anyone have the schematic for this pre to share?

Thanks
Lars

Hi, unfortunately I never found a suitable replacement with MN type tapper that would fit so I ended up permanently bypassing.
Probably the subwoofer pot should be easier to identify a replacement.
Unfortunately I no longer have the pre readily available. Maybe if you could post a close-up picture of pot markings someone can help identify a replacement.
