I'm sure someone will correct me if I am wrong but I'm prety sure that Mk VI's are not fitted with that. there's just an arm that is attached to the C# hinge that goes underneath the B key arm and the linkage is usually cork (i use hicotex here)
I'm sure someone will correct me if I am wrong but I'm prety sure that Mk VI's are not fitted with that. there's just an arm that is attached to the C# hinge that goes underneath the B key arm and the linkage is usually cork (i use hicotex here)There is an adjusting screw connected to the B key that is pressing on a part connected to the C# key. I assume you are talking about the Mark VI in your signature but I'm going by an alto I have here (not Mark VI) which is probably about the same. Press the C# and B keys seprately and together and you will notice how this mechanism works.
