I bought a St. Peters. from Tuba.com in April. I decided to buy the
"Nickel+ german machine" model.
This horn sound Great. The nickel plate is a little weak but the price is good.The only problem is with the rotary valves. The german machine" is realy good but the rotors are a little too small for the size of the 'hole' (sorry for the english). The result is that they:
1) do not keep the pressure very well (but this is not a problem because the horn play well in any case)
2) are noisness.
Is it possible to do something to resolve this problem i.e. to change the mobil parts inside the rotary valves or to envelope these parts in some way?
Thanks for help.
