Seek Pedal Only Duo-Art Grand Tubing Diagram
By Edward Baylis
Hi All, I am looking for help with a tubing diagram for a Weber
Grand pedal-only Duo-Art. I need confirmation of the all small tubing
including from function switch to Duo-Art box and expression box.
Also, how many ports are there on a grand Half-Duo-Art switch?
The expression box fitted has four small tube nipples: two are bass
and treble to primary valve box, another links to the motor governor,
and I'm not sure where the last nipple connects (shuts off two valves
in Duo-Art box). There is also a small nipple out of the main
governor; what does it supply?
I suspect the instrument I am working on has been altered, including
the installation of an 8-port function switch (e.g., from an upright
Duo-Art). The primary valve box appears to be from an upright --
it contains double-hole tracking valves and Theme valves only. There
is no sustain pneumatic valve. Any help would be appreciated.
