Need Help on my ML 26

I was listening to my system when I realized that my left channel had more gain then my right. I traced the problem back to the preamp. Now I am stuck, I don't have a schematic so I can't troubleshoot it. I suspect that a transistor might be the culprit.
Is there anyone out there who had this happen to them or familiar with the topography of the mother board so you can provide me with some ideas where to probe? If you happen to have a schematic, could I get a copy of that schematic?
Any help that would make my 26 healthy again will be greatly appreciated.

I have a 26s and I maybe I can help you but first: Is this "problem" something that just happened (all was OK before?) or did you just notice it?

thanks Neil for responding so quickly.
the problem just happened. I suspect that a part is starting to fail since my right channel gain is less then my left but not completely gone.

This c-o-u-l-d be carbon deposits or trace deterioration on the pot's sweeper. Usually it's at a certain area on the sweeper. But this would happen slowly over time-- not suddenly.
