Do you mean the arm that closes the lower octave pad when A2 and higher are played?
I think that should be "is played"?Do you mean the arm that closes the lower octave pad when A2 and higher are played?
I see the small plastic sleeve. That tubing is also used in mechanisms for the right hand side keys. I would think if the tubing is worn that's the problem. Replace it?When I lift my LH 3rd finger the valve for the "A" tone hole opens sluggishly like there is some form of friction. Without the octave key - it is smooth and no feel (and sound) of friction. I took apart the octave mechanism and the only thing I could find that was maybe the culprit was the plastic sleeve that is on the tiny rod that ties the two rods together. The plactic sleeve seems worn. Probably a poor explanation but all my saxes have that or similar sleeve on the octave mech.
Any ideas or thoughts? I put it back together and it is still the same. I oiled the usual joints in the octave system.....
