[pianotech] Yamaha p22

[Tom Gorley]

I want to make a correction.  I went to bed last night and thought, OMG!  I wrote A61 while I was picturing A-73 in my mind.  A-61 has a damper, so make that A73 that was sounding off.

Normally this area isn't a problem, but on this piano I had to insert stringing braid to quiet it down.
