First, Make sure that the hose connecting that note/valve to the tracker
bar isn't off at one end or even split at the nipple or a bend.  If you
can tell me which note cyphers, I can tell you which tube.

I looked at the pictures I took of a couple of Hofbauer organs
I restored and there are 20 little buttons that protrude out the bottom
of the wind chest, one for each note.  If you push up on one, that note
plays.

I think that the only way to access this area is from the back of the
chest, which is way down at the bottom, just a small space in front of
the bellows.

You might be able to work something like a coat hanger with a 90-degree
bend (with about a 3-inch leg) down there.  Hold the main part vertical
and then turn it to sweep the bent end under the chest to dislodge a
peanut or whatever.  Or how about using compressed air?

Watch out that you don't cause damage while you're messing around with
the insides of the organ.

Cipher: A note that continues to sound in a pipe organ when the organist
does not intend for it to sound.  Perhaps this is actually a psychological
problem.  Are you certain that you really want it to stop playing?
