[GFi5607775@AOL.COM]

Clunk sound, Steinway Action:

Check the Jack first, lettoff buttons, and action felts on the key(s).

If the action is out, check the damper lifers "by hand" I just "flick them up"
Does you action have the Sostinuto on the action?

Does the Sostinuto work? Check here before you pull the action is so.
