My valves are a bit stiff. After a few hours of playing my 4th valve finger (in particular) gets quite tired. I've lubricated and cleaned inside and out thoroughly. The response is fine: fast and reliable; it's just a bit uncomfortable! Will slightly lighter rotor springs help, or will that just slow the action down?
I've sourced a few spring manufacturers, but for US $45 I'm not willing to give it a try!
I haven't had any luck finding ready-made tuba springs on-line. I've searched major manufacturers (no replies to E-mails) and music stores.
Anyway, without knowing specifically if there's a lighter spring than the one that comes stock with my horn (Yamaha YCB-661), once again I'm purchasing blind.
Thanks for any advice/information you may offer,
