"Have you noticed that the keys on your classic synth have become noisy, loose, and generally sloppy? If so, you are not alone. Age has deteriorated the critical rubber bushings which are the "heart & soul" of the Pratt-Read key mechanism, the action used in many of the great synths of the past, including the Prophet-5, OB-Xa, PPG, most ARPs, and the Minimoog. This degradation occurs over time, as many of these instruments are now 15-30 years old. Because of the gradual nature of this effect, we have forgotten how
silky smooth these keyboard mechanisms felt when they were new. The good news is that there is a solution available now."

If you ever wondered what bushings look like, here are a couple of shots from
Synthesizer Bushings at High Spies. You can also find bushings and other keyboard repair kits available
here (note there are some synths for sale there as well).
