[pianotech] Noisy dampers

Hi Chuck:

Sounds like hard damper felt.  Replace it and adjust.  Best to do the whole
set.

Hi group,
I'm working on a Kimball baby grand with noisy damper felts.  No noise 
upon depressing the damper pedal or any individual key, but a "rattling" 
or "buzzing" noise upon release in the monochord and bichord area.  
Trichords are all fine.  Removing the action and manually lifting the 
damper heads produces the same noise.  It's not a ringing damper--it's 
very abrupt--just a metallic "clunk" upon the damper's return.
I'd welcome any suggestions on how to further diagnose or cure these 
little beasts.
Thanks,
