<< I tune a Yamaha G1 (1963) for a local piano teacher who has been 
complaining 
 of a buzzing key (D4).  It seems that the buzzing is being produced by the 
 damper, a trichord wedge, as the felt settles between the vibrating strings. 
   The damper appears to be aligned to the strings and the dampers overall 
 are in decent regulation.  There are several other trichord dampers that 
 buzz in this manner, but to a lesser degree.
 
 Is it a possibility that the problem stems from the consistency of the aging 
 damper felt?  Could the design of the piano (trichord wedges to F4) also be 
 a contributing factor?
 
 Any ideas to cure this annoying bzzzzz would be much appreciated!
 
 Many thanks,

The problem is probably hard felt. Try filing the felt, or even voicing it. 
Remove the damper, and using a file, remove some of the felt, especially in 
the middle. if that didn't do it, take a voicing tool, and just fluff up the 
felt a little. If none of that works, replace the felt.
