Sticking Damper in Young Chang GS-150

[John Ross]

MessageI had a problem with sticking dampers on a small YC grand. It ended up being a weight coming out of the underlever, and binding on the note alongside.
Off course it could just be a tight bushing where the wire goes through. (Where is Merle Mason's book when I need it)

  Hi,

  The damper in the G5 region of a Young Chang model GS-150 small grand piano gets stuck open if you hit the key pretty hard (it must be pushed back down by hand). A medium hit on the key seems to jam the hammer for 1 second but it returns to the down position. Even if I hit the key lightly I observed some binging of the damper before it returned to the down position.

  What could be the problem, does the action have to be taken out of the piano for repair?

  Thanks,

  Marc
