And ... it is quite easy for gnarly upright damper felts to refuse to 
seat properly without a bit of help. Jonathan should start by finding 
out whether it's 100% of the dampers or one or a few that are ringing. 
Just one misaligned wedge felt at the break can make a lot of noise. 
Likewise the low bass dampers could be rubbing against each other, 
causing them to sustain. Sometimes flicking the offending damper a few 
times gets to seat acceptably. Sometimes you'll be able to unkink an 
irregular damper wedge.
It might be necessary to replace one or two of the original felt.
As others have suggested -- was there anything you did to the piano 
(adjust lost motion, tighten screws) beyond removing and reinstalling 
the action?

And as Tom D. suggested -- join the Guild, get the CDs, attend regional 
& international seminars ASAP!
