List,
 The piano Chickering console, aprox 44" 1930's.  in spite of
having exceptionally good springs, adequate lost motion in the pedal rods,
adequate lost motion in the whip/capstan, adequate lost motion with the
damper
spoon, etc. With the pedal rods out, and the action frame snagged tight, I
still get after ring. It's annoying, so it must be repaired/regulated.

Patrick,
If the damper springs are _too_ tight, there can be an isolating effect on
the lower portion of the string. The damper will act as the top termination
and you get the lower portion vibrating.

Try voicing the damper as well. If they've become a bit hard, get into them
with your picker and soften them up a little

Just a couple of thoughts
