I have a 983 that I need to get the first valve vented. Has anyone ever done this to a compensating horn? The tech who is going to do it is a friend of mine, I just wanted to make his job a bit easier. I'm guessing this could be a bit tricky(er) that the usual piston tubas, anyone have a pic of (any) compensated horn vented?
thanx
