Yup. Did an ultra-super-careful keyleveling and lost
motion adjustment today ( using the
press-on-the-back-of-the-key-method ). Spent 5-1/2
hours on just these two items, and the bobbling DID go
away. But the letoff is still 5 to 10 mm throughout
the keyboard, so I would be very surprised if some
bobbling did not return once I set this to the 1.5 to
3 mm authorized by Yamaha.
I have never seen a piano so unforgiving, become
so unplayable, with such slight lost motion! I still
think that an overly fluffy buckskin, a too sharp edge
on the jack tip and some fricative aspect between the
bucksin and plastic jack are culpable.
It made me think of a Jaguar automobile: Fun to drive
when in adjustment, but easily knocked out of whack.
Will keep y'all posted.
Thanks!
