damper problem

[Mary Smith]

Yeah, I agree with what Ed said about letting the dampers settle in for a 
bit (praying never hurts, either...). Also, be aware that levelling strings 
can impact damping, for better or for worse. You might check string level 
just to be sure the dampers are properly mated. And be sure to check the 
spacing of the strings through the agraffes. You don't mention what area of 
the piano is having this problem, but I am guessing it is in the trichord 
wedges just above the tenor break. If the string spacing is uneven, then 
the tips of the trichord wedge dampers may not fit as snugly on one side as 
on the other. You can give judicious squeezes to the "fat" side of the 
damper felt (out of the piano, of course).
