A contair, I beg to differ.
Altghough the caseings might be dented, other then that
there's nothing to go wrong with a tapered rotary valve.
If the rotor gets too loose a good tech. can usually
recondition them by swedging them.
Yes it dosn't cure all but most tubas are renewed
to near perfect in miniutes !
When the casing to too far gone, they will just need
re-swedging much sooner.
It isn't unheard of to fing a rotary tuba over one hundred
years old that plays fine.
That's bin My experince FWIW.
