I was called to tune a rebuilt Fischer Ampico grand piano. The
customer says it normally plays too loudly. Now the notes stopped
playing last week even though everything else operates normally.

The roll starts then the pump lugs down and can turn the roll to the
end and rewind and shut off automatically. But the notes don't play.

I checked all tubing connections. I can get some treble notes to
barely play by depressing the expression control bellows. The pump
belt is not slipping. I have tubing diagrams and some control diagrams
and pictures but need direction.
