I have not worked on an Art Echo for many years, and I can't remember
if I ever had literature on that system and can't find it if I did.
Does anyone know of a good source for ArtEcho or Art Apollo technical
literature, either paper or downloadable?

I have a customer with a Melville Clark Apollo grand that was tubed
by some clown who obviously had no schematic either.  I do know enough
to know that his tubing is all wrong.  I have one that is perfectly
restored in storage but I would rather not draw that one out to take to
the customers house.  His has nipples with nothing on them coming out
of the expression box and he lost the bass & treble soft pneumatics.
I had to make them.  While trying to hook the new ones up I discovered
that their tubes to the tracker bar, instead came out of the expression
box.  Right?  I don't think so!
