I currently have a four Vavle F tuba that I enjoy playing and have good control of, but I would like to add a fifth valve to the horn itself and improve its low range. I am having a problem finding a rotor and casing to use to undertake this project. I realize many of you modify your tubas, and I was wondering if anyone could suggest where to locate the rotor and casing. I would also like to know about how much I should look to spend for this.
Oh, it is an early seventies Amati, and I know most Amatis of that era had intonation problems, but it actually is pretty solid except for the fourth vavle intonation, which I am currently addressing.
Thanks in advance for any advice

Call Dillon Music in NJ. They are dealers, and I'm sure they can get the rotor. VF Cerveny/Amati also has a warehouse (I think) in NJ as well. Shouldn' cost too much, especially if you know the model number!
Otherwise, you'll have to find someone (dillon again?) who can get a rotor from Germany.
Oh - Kanstul might be able to help as well...

Lee Stofer, who periodically posts here, does very fine work. My last F Tuba was a Zeiss Master Modelle that he added a 5th valve to. It was expertly done, esthetically easy on the eyes, and used great parts. I believe he used a Meinl valve. Don't know where you are in relationship to Iowa, but he is the man to do the job.

Thank-you, Chuck.
It should not be too hard to get a .770" bore rotor assembly from Amati/Cerveny. It you go to their website and look at the tubas, find the model that has the valve set-up that you like, and that will most likely make for an easy modification.
I have used several different rotors on tubas where I've added a rotor. For an Alexander, I always use an Alexander rotor, and try to make it look factory-original. For Chuck's Ziess F tuba, I got a Meinl-Weston unit, I believe, as it was most cost-effective and a very good rotor as well.
I don't think that a Kanstul rotor would work on the Amati, as Kanstul does not make a rotor that size. I think that a rotor from Amati-Cerveny would be the most cost-effective as well as providing the desired effect.
