Several questions for the experts; Since I don't have a picture or an
original to go by, several aspects of the construction of the machine
are a mystery to me.
First of all, is there (was there) any method of adjusting the distance
between the tops of the rods which push the valves in the wind chest
and the fingers on the vacuum pneumatics?
Second, how much action (lift?) should there be for the vacuum pouch
valves. Mine seem to have only about 1/32" and this doesn't seem like
it's enough to allow sufficient vacuum through into the pneumatics.
Looks like someone added gaskets which are too thick to the valve tops.
Third; does anyone have a chart which would tell me which hole in the
tracker bar goes to which flute, trombone, drum, etc.
