Hi Mike,
I think that the important bit is the "B10K".. 'A' and 'B' stand for Lin and Log I believe, and '10K' is the value. I'd say your OK and it will work.
The 4M and 4Y could be some manufacturing codes..!? ... having said all that I could well be wrong...;c)
Cheers,
TOM

Does anybody know if this will work? The picture on e-bay looks the same as the one that I have in my CS80. Does anybody know if there is a critical difference?
