---------------------- multipart/alternative attachment Greetings, I was called to service a 5' Young Chang grand piano the other day which was abused at a party. One guy played the keys harshly while the other put his hand over top of the strings above the hammers. Clearly, the delivery of the power from the key stroke was not allowed to flow in the manner for which it was designed, energizing the string properly (as the string was restrained by the "assisting" party of this mahem) and the energy recoiled back into the wippen. Now, the key when played softly, strikes the string, but does not fully return to rest on it's hammer pad. Key acts normal on mezzo-forte and forte blows. Also, I removed the action drawer and depressed the key while outside the piano, the key does not cause the hammer to have as much upward power (wont fly up as hard) as the other keys that are not affected. In other words the power stroke has lost it's 'umph'. My guess is that the repetition spring was compressed/ slightly bent. I dont have a grand action model, which would be instrumental in solving this thing. Any suggestions? Thanks in advance.
