ringing dampers

[Paul McCloud]

Be sure to check that the dampers and trapwork are regulated properly.
Press on the string(s) and see if the dampers move along with the wire
as you push.  If they don't, the damper levers are resting on the damper
tray.  They should not.  See that the damper pedal has about 1/4" of
travel before any dampers move.  See that the dampers lift in the proper
timing, ie., they begin to rise as the hammer is about 1/3 the way to
the string.  If they don't, the damper levers may be resting on the back
of the keys.
    There has also been recent discussion of different replacement felts
in the dampers, but this may not be possible or practical in your case.
    Changing out and/or adding extra components may not be necessary if
you make sure the mechanism that is there is in proper regulation.
