For those of you familiar with the Seeburg Celesta, I'd like to
get your opinion as to the following question.

Would the stack valves be able to handle the load of the small
vacuum-to-pressure interface pneumatics, as well as pull pouches
to a xylophone, in a typical Seeburg orchestrion fashion?

Mine is missing the primary chest, which isolates everything, but
as this will not be hand played I thought I would plumb the piano
stack like any other Seeburg.  My concern is the spring tension on
the tiny interface pneumatics, which would make this arrangement
inadvisable, especially on low vacuum to the piano stack.

Thank you,
Stephen Kent Goodman
