Simon,

The sensors in mine all were fine (actually, it's a really long story).  
However, I have seen sensor boards that looked like they had some kind 
of corrosion on the circuit board contacts under the rubber pad, 
possibly from the rubber pad decomposing.  They are easy to disassemble 
and clean.  Take a look at sensor_guts.jpg under Files on the Yahoo site.

On the other hand, the Roland A-50 I'm fixing up has thick felt glued 
down along the whole length of the pressure sensing circuit boards.  I'm 
afraid if I pull any of it up I'll destroy the whole thing!  The CS-80 
is so much easier and more fun to work on.  Of course, it's about 10 
times as big and heavy.
