Don't forget to check the dummy damper. If it isn't working properly it can place excess tension on the damper rod or, not enough. Also check for damper follow through which I'm sure you already have.

There are two problems. The action is heavy. Everything is regulated the way it is supposed to be. The only thing I can figure out is that the damper springs are too strong. But that leads me to the second problem. Although each note dampens, there is a general after ring in the whole piano. I can get it to stop by putting my hands on the bass string. What I'm afraid of is if I weaken the damper springs, the after ring will get worse. The damper felts are OK, a little noisy, but nothing unusual. I did have to replace one damper flange because the spring had broken due to rust. Any ideas? Willem (Wim) Blees, RPT Piano Tuner/Technician 94-505 Kealakaa Str.
