Emu XL-7 & MP-7 User's Group

You could have a go at changing the encoder, but carefull soldering 
skills are reqired or damage will occur to the PCB. Not good.
Ive got proper desoldering equipment here and even with that 
sometimes parts can be a pain to get off.
That encoder should be easy though.
Try digikey in the states for a replacement. Think ive seen them on 
ebay at an inflated price as well. Other emu gear uses the same style 
encoder.

You could try cleaning it first, it can be a solution for a short 
time, maybe longer.
Get some contact cleaner, something like swish or craig deoxit D5 or 
at a push servisol contact cleaner.
You might get lucky, but if its worn out then its worn out!
I got lucky with mine, its still working after a couple of years.
Look in the photos section under miscellaneous and find the XL7 
encoder picture. It shows you where to squirt the cleaner.
Hope that helps :o)
