This is regarding yesterday's post by Tony Leine in response to his
issue of several keys on his player ciphering in the treble as soon
as suction is supplied.  Tony says his player piano is a Cunningham,
so I am going to assume it's either a Standard or Auto-Deluxe action.
Both are identical as far as we are concerned with this issue.

I think the problem is that the channel boards which convey the tracker
bar signal to the valves are leaking at one of the leather-gasketed
joints.  If this is a single-valve action, it should be very easy to
remedy.

Pull the front off the piano, and just back of the music desk you'll
see a row of vertically-fitted #6 oval-head wood screws spaced about
5 inches apart, all the way across the front ledge of the player action.
Give each of these screws in the treble area a slight tightening, and
you should see your problem disappear.  Don't over tighten them -- they
will strip easily -- so just get them snug.  Only a small amount of
tightening should eliminate the issue if this is the fault.

If this is a double-valve player action with primaries on top of the
player stack, you'll also see an additional double row of identical
screws, horizontally-fitted, in a sort of a slight zig-zag (up and down)
pattern on the front of the primary chest, located directly above the
previously discussed screws.  Give these a tighten also.  Again, do not
over tighten if your symptom does not disappear immediately upon
tightening.

If this does not solve the problem, the issue lies on the rear of the
player action, and unfortunately will necessitate removing the top
player action and investigating the screws, gaskets, and seal cloth on
the back side of same.

Hopefully the above outlined procedure will fix it, as it usually does
in my experience.
