If I puch a little bit on the damper itself, sounding stops immediatly after I stop playing the key. Is the damper-felt to soft or has the damper-action not enough wait? I've placed them correctly on the same way an the same heigth as the old ones. How do I have to resolve this problem? >> Dear Peter A little more information might be helpful here. Is this a less than 5 ft Zimmerman, say 20 years old or less? Why did the damper felt need to be changed? Were notes ringing through before you changed felt? Are all the dampers leaking, or just the singles, or bi-chord or the flat felts? Did you re-bush the damper guide rail? Are the damper wires moving freely and square? Have you checked the string leveling? Check the pinning on the underlevers? Is the lifter tray supporting the underlevers in any way? These are just a few of the possible causes. I haven't seen any of these little beasties for a while but if it's the ones I'm thinking of , well , they weren't ever quite perfect. Touch your finger to one side or the other of a unison. See which string (s) is leaking. Sometimes a piece a yarn or carpet thread can be inserted in a tri-chord felt to spread the width. Do they sound longer when using the pedal than playing just a chord or note? Check these things and let us know Best Regards Mark Ritchie RPT Cols OH
