     Give it a good solid whack with a hammer.  Usually takes care of the 
     problem with one whack.  Or do the decent thing and toss it into the nearest 


I know you were being cute, but do you know how much a good old 4 rotor tuba may be
worth? Try $2000 to $10,000 US depending on the maker. 

anyway, rotor valves are tricky - they are usually hand lapped to fit specific valve
housings but on older horns I have played it is more often the linkage or springs
that cause the hang-up. It may need a full linkage replacement with ball and socket
levers and new springs to replace the clockwork style coils. There are good repair
shops that can do this - Randy, where are you located?
