Player piano problem

[Patrick Poulson]

Berley: Thanks for the tip. Actually, the notes are A2 and D3, so not adjacent. I will report back after I see the piano tomorrow.

  Patrick,
  There is leak between the tracker bar holes for the two notes and their valves (primary if a two valve stack). Being there are two notes together, I would suspect someone might have lifted the stack at that end and either broke lead tubing, or dislodged rubber tubing. Also the nipples might be loose (they are sealed with burnt shellac).

  Suspect also when two adjacent notes are involved, is the gasket joint between two component boards, or even a screw hole, left by a forgotten screw. When the screw is "in", it seals a leak, but opens one up when removed. Check for loose or missing screws in the sometimes-many screwed-together boards at that side of the stack.

  Another thing to check is some debris or damage to the valves....mice can do that!
