You got to start somewhere...

We see those Exclusiv models quite a lot here in the Netherlands indeed, 5 valves is a rarity thought, mostly 3 valve models.

Almost all are nickel plated

Theseus's Tuba

I have it now! It's a Cerveny Tuba and it has an AMAZING sound and tuning!


Aha, you got it so quickly!
Very cool tuba. Odd that the seller called it a Swiss tuba. Maybe a Swiss retailer that sold it initially?
How old is it? Quite different design to 'modern ...

Large format 3D printers (~325 mm³) are becoming more accessible now, before it was either high end professional ($$$) or entry level hobbyist machines.

To work out a good design you need someone with a large format printer that can iterate and fine-tune the design.

Edit: link is dead, it's gone from the site unfortunately..

I looked on various 3D print websites but can only find the 7506 hangers, not the 7502.

3D printed is less sturdy then injection molded of course, but material cost is so low you can easily get multiples.

I can confirm the measurements, my D6 shank starts at 13.6mm

Sorry, didn't get to it today, busy day...

It is not listed in their (old) catalog, most likely euro
I have one here, I can take some measurements tomorrow

I can agree, I was in the 4th row twice. Those trumpets produce lot of sound

Interested in an OG ultimate for my Amati B&F Kaiser. What would the price, and shipping, be to this side of the pond?

Ah yes, woodwind parts make sense, those are full of posts and linkage rods

Ah, that explains, I have seen more of the MW version of this design

I thought that the slide in front the bell was the 3rd slide, so I guess I did learn something from this

I specifically asked to leave the stops raw brass this tuba has multiple raw brass accents (receiver, paddle bar and linkages) and I like how it combines with the nickel plating.

The stops are nice and quiet now, bit i might put one some clear heat shrink tube

My F tuba also has a similar slide ...

My Amati B&F 69 Kaiser had strings attached to the 1st and 4th slides as slide stops, I never liked these and also for the 4th slide it was on the wrong side and the attachment point pushed into my arm which wasn't very comfortable.
Because of the way I hold the tuba I didn't need the handle on the ...

My Amati 6/4 has an aftermarket 4th valve. It is an "open wrap" and not stuffy at all.


So did you only change the rotor or the casihg as well?
Also where did you buy an aftermarket rotor? I can't seem to find it on the internet. I will first check for any leaks/missaligments, but if that ...

My Amati B&F Kaiser is currently at Adams to have some work done. The handle on the 1st slide is being moved to the 3rd slide (which is behind the 1st). Both slides can then be manipulated from the same hand position.

I do generally need to push the 1st slide in (for the C in the staff) and the 3rd ...
