Re: Mahler Symphony no. 1 Tuba Choice (Poll)

The last time I saw this performed, it was the San Francisco symphony sometime around 2018. Jeff Anderson used his F tuba (some kind of rotary B&S, not sure which model) for the solo, and his C (he played a PT6 at the time, still might) or the rest. The performance was, not surprisingly, awesome ...

Re: PT-8 8k

I played a PT8 at Midwest in the elephant room, and own a Symphonie. I don't have a perfect basis for comparison but I will throw some thoughts out there all the same. To be really precise I'd definitely want them side get side.

I truly enjoyed playing both horns. Effortless response up and down ...

Re: Cerveny 686 Fourth Slide Lengthening Advice

I ended up going with the Bloke approach here and it worked beautifully. Cerveny proved already lacquered parts, making the work straightforward. After this plus shortening the first valve to allow an in tune third line D, I'm mad at myself for not having this this work done sooner. An easy to play ...

Grant Park orchestra is a blast! Concerts are free right in the center of downtown, mostly in the early evening, just bring a picnic blanket. You can also purchase reserved seats. They have free open rehearsals outdoors during the middle of the day, which are also a lot of fun to observe.

Re: Sam Gnagey's Cerveny/Amati 681 CC, $2,700 (Fort Wayne, IN/FB)

I'd love to get one of these, my early 2000s era 686 (larger bell but same bore, good intonation characteristics) and the new Lidl versions (which have a larger bore) for a side by side, I'm really curious how they compare.

Re: Tweaking instrument production with software

bloke , the open source software definitely makes a constant temperature assumption. My training is in a different kind of mathematics, but taking a glance at how the math/software works, extending it to account for different temperatures at different parts of the tube wouldn't be too hard, could ...

Re: Tweaking instrument production with software

There's also an open source instrument design software for Python available, developed out of a lab in France, called openwind. It doesn't have the cool hardware that BIAS has or even a UI, definitely less approachable, but does have the ability to predict intonation characteristics given a geometry ...

Re: Identify B&S CC

This is a funny one! It looks like either a PT3 or Symphonie 3/4 C tuba.

The Symphonie 3/4 C tuba almost always has a kranz, and has the F tuba / Symphonie valveset, which is conical (17-21mm) bore and has the 5th and 1st valves separated just like the Symphonie F tuba.
PT3s usually have no kranz ...

It has some odd characteristics for a B and S, 45 degree exit from the valveset, straight approach at the top, and a very long leadpipe ...

Re: Cerveny 686 Fourth Slide Lengthening Advice

Thanks to all for your advice! The third slide is the same length as the fourth, so switching doesn't help. I'll be going with the folded slide.

Cerveny 686 Fourth Slide Lengthening Advice

I have a 90s Cerveny 686 C tuba (Sanders is the stencil name) that is a great player, but unfortunately has a pitifully short fourth slide, equivalent to 1+3 with the first slide pushed almost all the way in. It needs about 4 inches more total of length to be in tune, so something like 2 inches more ...

Re: Who rebuilds rotary valves?

I think I might have bid against you for that Weltklang 104! I remember hearing that Dan Oberloh is set up to do this as well, but a rebuild is unlikely to save you much money.

I had 2 leaky valves on my Symphonie, and after conversations with multiple instrument repair folks, went with replacement ...

B and S Symphonie Valve Replacement Project Diary

A detailed writeup is below, but TLDR, if the rotors of a good tuba are worn, having a skilled repairman replace the valves is absolutely worth the investment. Recent changes in tariff policy add a small to moderate complication to trying to repeat this project again in the near future.

Re: F for less than that price of my kidneys

Congratulations on the new axe! A nice F tuba feels like jumping into a Miata after years of driving a Suburban. I remember being shocked at how easy stuff like Kopprasch or Rochut was to execute on mine.

From personal experience, rotary F tubas often don't respond great with funnelish mouthpieces ...

Re: F for less than that price of my kidneys

To drag this back on topic, if you're looking under 5k for an F tuba, even the higher quality Chinese made instruments like Eastman or JP are usually out of reach (occasionally one might pop up used barely under the 5k mark).

I can't think of any options outside of Jinbao/Mackbrass/Wessex copies ...
