Duo-Art No Longer Plays After a Couple Years
By David Zitzmann
Hello all, After two years of sitting (a long story), the suction
no longer goes through the expression box unless I push up on the
Accompaniment bellows a little; then it works. With a new roll
repeat the process.
The rotary pump is producing vacuum, but it is not passing it through
to the stack. I was hoping someone could give me a direction as to
where to start. The crash valve, maybe? The motor works just fine
during play and re-roll. The piano has not been moved at all so
nothing has been jostled.
