York three (and rotor) valve BBb

[tubalooney]

Hi everybody!
I am in the process of buying an unusual and very interesting BBb tuba.
It has been modified with a rotor valve to provide a fourth valve, an upright bell.
Does any one of the gurus out there have any views?
Kindest regards
Phillip

Cool! I remember there was an Eb Monster with the same mod on here a few years back.

Wide side of MTS. Why odd?

I have always wanted to try the fourth rotary valve thing. By putting it after the main tuning slide you enable the rotor and tubing to be bigger(more open) like everyone seems to be doing with 5th valves now. And there are so many incredible three valve American horns out there. I have a Martin Mammoth that I have been scheming to get this surgury done to.Your York is beautiful. Is that a Kanstul bell on it now? All the Best, Ed

Hi everyone, thanks for all your replies!
I haven't played the tuba yet next weekend hopefully!
The owner lives in London and he says he bought it off e bay and that the work was done by a specialist in London about four years ago but he doesn't know who.
Does anyone recognise this sort of work?
Has anyone seen it for sale before?
If I end up getting this horn I will certainly keep the original bell and perhaps work out some sort of collar arrangement so that I can exchange the bells over when I want to.
I'm looking forward to using it in a tuba quartet project I'm dreaming up
Thanks for all your ideas and help
Kind regards

Hi,
that's an valve location that's been around for a while,
look at the Melton Baer CC, Yamaha 826, Hirsbrunner HB50, Nirschl CC etc
Hirsbrunner were doing it back in the 80's..
I imagine that it allowed the fourth valve to have a wider bore better low range, less stuffy etc.
I couldn't say for real because I think this advert is a fraud.
I arranged for a good friend to go and test the tuba allegedly in Worthing in England, although it has been advertised in Germany, and the vendor never got back in contact.
This isn't the first time a German tuba player PM'd me to say that he had the same exeperience in Germany....
Shame I was really keen
keep your eyes peeled.
If anyone has any more information about this phantom tuba please pass it on.
Here is the advert that I found....

this one is Unna near Dortmund in the Northern Rhineland

and another!

this time in Rostok on the North Sea coast
also advertised on willhaben.at when I did an image search on google for York Monster 6/4 Grösse tuba

and he told me that the tuba was in London.....

Bizarre no?

All the best

Who made the bell?

Odd that the rotor is in that spot. Is this a 6/4?

and I forgot the Daddy of them all Arnold Jacobs' York 6/4 CC had a rotary valve on the wide side of the MTS. I wonder when that was done?
Back in the 40's...?
Keep on tuba-ing!
Cheers
