I sure don't know, I'm just here to mention that the tuba is a conical instrument (categorically speaking), so valve bore size depends a lot on where the valves are, in that conical profile. Its significance is a little ambiguous.;

That Martin 33 sounds kind of interesting. You might be able to ...

I don't know what to think, which is why I'm asking this wonderful panel of experts. I don't recall ever having dealt with tariffs before.


I admit I was surprised. I haven't dealt with tariffs per se, but I have deal with customs (Portugal, possibly as bad as it gets), and I don't recall the ...

A 6/4 Bremelo BBb tuba weighs about? @donn


Say what? You got me, I have no idea what that is. Weights I can report, approximately:

Conn 40K 4v sousaphone: 31 lbs
Kalison "Professional" (ha ha, anyway it's the big 5/4) 4v BBb: 24 lbs
Kanstul Model 66 5v Eb: 20 lbs.
Cavagnolo accordion (three ...

Yes, several, but Tubenet seems to be out of commission lately.

Kerosene is basically just impure paraffin lamp oil.


In case anyone is looking for clarity on this point, I understand "impure paraffin" to mean "not paraffin", right? If the product label says "paraffin" or "paraffinic", then it's 100% alkanes.

(Immaterial for me - I haven't found anything of ...

Yes - if it's really paraffin.

Lamp oil really only needs to burn when used in a lamp, and I've read enough stories about strong smells etc. here to make me suspect that some "lamp oil" is kerosene.

In any case, I would expect mineral oil or motor oil to mix equally well, and with motor oil of the ...

To seat another passenger -- I very much doubt they would do that, or even could. But the flight crew has the last word, and if they think it's a potential hazard in any way, they can say no. As I understand it.

Whether it's worth participating in today, or not, the site still has a lot of accumulated information from people who aren't here, or even alive, and at a casual look it isn't archived on web.archive.org (not the posts.) It would be a shame to see it go off to the bit recyclers.

just for the record, if I were going to play gypsy violin solos, it would be on a violin.


yeah...If some 350 lb. dude in a too-short T-shirt walked up to my restaurant table and commenced to playing Csárdás on his sousaphone, I'm pretty sure I'd leave...without paying.


Sure. I don't know ...

Though tubaforum.net may be a little eccentric on this point. It seems to me that most sites with authentication cookies will automatically switch you over to https:. Here, you stay on http:, with missing identity.

The names are similar by coincidence.

Romania is so named because it was a province of Rome back in the day (Dacia.) Romanian is a Romance language like Spanish and Italian.

Romani comes from rom which like many people's names for themselves, just means "man" in their Indo-Aryan language ...

Saw one of the university trumpet players who warned me that the brass players are expected to play different pitches harmonicas in one piece. When the students gave a bit of push back, they were told that they needed to embrace modern music.


Good for the students for pushing back.

I have ...

Just for curious, is there a mouthpiece comparator for tuba, like we have for trumpet? It's a incredible tool!!


No. Do you know where the data for that comes from? I could see a big tuba studio possibly might be interested in a task like this, but there are an awful lot of mouthpieces out there ...

Yes, the cross-section diagram HELLEBERG is presumably prior to the Precision Conn 2, and I think it would be fair to say that the edge is rounded about the same as the CONN 1, just rotated slightly inward because the cup profile is less conical at the top than the CONN 1. That geometrical factor is ...

Sharp rim? It depends on the year of manufacture. My Conn Helleberg 120S has a rim that is more like a Wick rim, slightly rounded and not sharp at all. I have played the sharp rims, but mine is not one of them.


Is your Helleberg mouthpiece new or vintage?

I don't know. I bought it used ...

For more on the subject of the Conn Helleberg, see The Conn Helleberg , from better days in the tuba online bulletin board scene.

I don't have a real Conn 120S, just a 7b and a FAXX 120S copy. They're probably not as sharp as the sharpest ever Hellebergs, but the rim is more than average flat and ...

Same in China actually. More factory robots than the rest of the world combined.

Tuba purchase as an investment sounds like a recipe for heartbreak, but then you can write a country western song and recover your money that way.

All we need is a handful of tubas that all sound exactly the same, in one alloy, and another handful of otherwise identical tubas made on the same line in the other alloy, that all sound exactly the same. Then perhaps you could note perceptible difference with some confidence.

Then you'd want to ...

so what happens if a british based company like Wessex or packer imports chinese horns to the UK, and then sells them to America? is there still the chinese tariff?


No. I mean, I am not an economist or anything, and I cast around for any specific treatment of this point and didn't find any, but ...
