[pianotech] Baldwin F Dampers

[Thomas Cole]

I'm going to replace dampers in a 50-year-old Baldwin grand. They're 
getting buzzy sounding when the key is released. My question is what is 
the best kind of felt to use. Last few jobs I've used Tokiwa but not too 
happy with the result.

Also any help with back action tweaking - are there springs on the 
underlevers?

TIA
