Couple links to ALPS encoders.

Doing job by myself i can test encoder types first one by one.
If it works the way i want i replace rest knowing that i would be happy with end results.

Changing all at once without knowing how those would actually feel is like lottery, IMHO.

What i'd like to know is which are physically and technically compatible ones?
ALPS pages inform whether they work incremental/absolute and their "Rotational torque" (resistance to twist) -and there are choises like standard / lightest(jog).

I guess that rotational torque is one of those things that needs to be tested.

DSI offered me some replacements earlier on which are the part number above - these have a split grey shaft and are harder to turn. the ones they replace for you, made by ALPS, have black shafts. i do not see any other part number markings on these. The ALPS have 24 detents. I looked on the Soundwell site and the part number is not listed (however in the past I remember it being listed). Perhaps they pulled it because of problems?
