[pianotech] keys acting odd

[Andrew Anderson]

Sounds like missing or loose bridle straps on the dampers.  Did the  
action return correctly onto the adjustment bolts on the bottom?  Are  
capstans centered under the sticker levers (side to side & on the felt  
front to back)?  You might want to bring your mentor or friend from  
your chapter to help trouble-shoot this.

Best of luck,
Andrew Anderson
