It sounds like this isn't the same as the patented system by Bill Youse. His was only patented in 1997. Perhaps he got the idea from this, or others like this piano.

David Ilvedson, RPT Pacifica, CA 94044 There was no need to adjust any of the keys. I'm not sure it the screws would turn, however, because the piano is old, and many parts are rusted. The piano is not in the best of shape, but it holds it tune. Willem (Wim) Blees, RPT Piano Tuner/Technician 94-505 Kealakaa Str.
