Hello everyone, I have a bit of a problem. I play a MW 2155 C tuba. It has 4 piston valves, and the 5th valve is a rotor. Today while I was practicing, the 5th valve just stopped working, as in, it is now stuck and will not move. I put the horn in a hot bath, thinking that maybe some gunk was stuck in it, but that did not fix the problem.
If anyone has any ideas, other than going to a repairman, it would really help.
Thanks to all.
