Ok, thanks! I will ask our technical department at our university if they can have a look inside these OMP's ... should be fun for them ;)

I have no idea what kind of resistors are in the Newton, but carbon resistors will change over time and hot/cold cycles.  It may be possible to fix them, but finding a part that fits the physical space and lead position is always an issue. Solder joints are also subject to corrosion [increasing resistance].  Analog sound and power supply circuits are unforgiving.
