Hi All,  Regarding Niels Berkers posting about his weak player
piano, I would suggest performing the numerous tests with are
listed at  http://www.player-care.com/test_me.html

As for the bleed cups being loose, that's nearly impossible.
As for determining the player mechanism inside the piano,
go to  http://www.player-care.com/makers.html

Be sure to read the information at the top of the page...first.

Musically,
