1) the strings need to be kept tight to stop the strings arms from 'hopping' causing the string to come off the stop arm by looping over the top.

I think this has happened for two reasons. There have been some complaints about the strings breaking. I like the string action because it is a harmonic force on the stop arm rather than a 'bang, bang' back and forth action. Most of the conversions I've seen weren't very good and tended to make the paddle stroke longer. Marzan owners have tried various ways to change the string linkage over to other forms of mechanical links. One would think that in the short span when these horns were made that there would not have been any manufacturing changes. I had two BBb 'slant-rotor' horns here that were not exactly the same. The taper of the bell stem is not the same for both horns. The stem end of the bell is 5.33' diameter on the BBb and only 5.01' diameter on the CC. When was it made? Phillip vbmodified.Īlthough the flares are the same (19') and the overall length are the same (27 1/2'). Is the 967T which is the classic 967 model with a new addition: the famous tuning slide trigger from the Prestige euphonium. Take a look at just the bells in the above images. But I've not had much experience with the BBb and CC ones next to each other. I've probably seen, worked on, and played more of these horns that anyone other than the folks who made them in the late sixties and early seventies. The tuning circuits are proportionally shorter on the CC horn. A BBb tuba is roughly eighteen feet from the mouthpiece to the end of the bell while the CC is about two feet shorter.

You can clearly see in the two imaged below that about the only parts that are shared are the rotors and valve circuits. The differences are not obvious unless you happen to see a BBb and a CC side-by-side. At first glance, the CC versions appear to be just 'cut' versions of the BBb horns. I figure it was about time to share some recent discoveries about the differences between the Bohm & Meinl-built 'slant-rotor- BBb and CC horns. I haven't updated this 'Marzan' page for some time and since repair work is an ongoing learning experience. Please send it to me for inclusion on this page. If I don't already have information about your Marzan horn.
