I have been wanting to service my instrument recently and have difficulty getting spares for my Maestro YEB-632S tuba. Only things I managed to get were valve guides, but others like springs seem not to be stocked by anyone and have to wait until they are shipped in (4-5 weeks). Anyone know reliable stockists of Yamaha spares? p.s., can one of the Mods change the title of this thread? Cheers! Edit: Done! (dyl) ... cheers!
