I have used this tool (pliers wrench in English?) to slightly tighten valve linkage rivets with little play should clicking appear. I found I have to take care not to tilt while pressing and evenly press the rivet head. So far this worked for my linkage issues.

I regularly face a similar challenge in my local concert band.

Any decent large 5/4 to 6/4 german style BBb (I have a "almost no name Graslitz-style 6/4") with a mouthpiece as large as you can handle (I use a Giddings Szentpali CC) to maintain and control a tight dark sound will help. E.g. a ...

I meant the opposite of open -- won't even play until you figure it out.


Then we missunderstood. Given me as a player with my mouthpiece (Warburton Demondrae - need the small shank version for the Miraphone), both the Alex and the Miraphone share the open, definitely not stuffy low range ...

Interesting what you say about the low range, because my 151 has a low range that is like a rotary F tuba on steroids. Once you figure out how to play it (not like a euphonium) it does have quite a sound. I have the four valve version, which has never bothered me with tubas.


Thanks! I think ...

Here's an equivalent from Miraphone for sale in C. The body is slightly smaller. I personally own a similar early 56A nickel plated and in Bb.

Gebr. Alexander have the 5V Bb version in (I think in goldbrass) in their showroom ...

From my rather long term experience (approx. 20 years) with the original 164 I can highly recommend the PT/RT AMH Paul der Große Pro.

Despite the discussion here about large throat size this is a really good match in sound (feedback from colleagues and conductors) and light response throughout the ...

For the trombones I think the valveless are better for beginners, it has proved troublesome to teach the far out positions later when a student started (too young) on a trigger trombone.

As low notes fingerings change fundamentally with the 4th, the same is true for beginners who have to add the ...

I'd rather think it's from a smaller independent GDR/Czech workshop or a home builder in the surroundings of Amati, Czerveny & Co.. The 3rd valve tubing as seen from the front looks uncommon for an industrial instrument. The known standard series do have straight downwards tubing there.

Could be a Czech or former GDR instrument labeled by the importer. I think close up pictures of the valves and linkages and a picture of the back side tubing would be helpful to identify a possible workshop. If it is Amati / Cerveny / Weltklang derived, there are sure some experts here who can help ...

The Perantucci AMH Paul der Große Pro seems to feature your needs except for the diameter. It's larger but very appropriate giving the size of instruments it's meant for. Intonationwise, size parameters seem to be very much balanced.

The form factor should be not so far away from the Thein RCC you ...

Cerveny offers a very interesting 6/4 BBb alternative at a fair price level still today:

I add my comments as it might be useful when scanning the high grade 5/4 to 6/4 BBb rotary market which I understand is the thread openers idea.

I can second this:


A 19mm bore (tiny for a 5/4 tuba) makes it appear stuffy upon first contact, either. But with time, one realiszes this provides ...

I can confirm your observation and I do see the cause in the layout of the instruments. Playing a Besson 3+1 BBb and a 4 valve rotary Kaiser, I experience the same difference regarding the amount of spit. The Besson will be retrofitted with Saturn Waterkeys for all valves as my elder 17" version ...

The Perantucci AMH "Paul der Große" is one of my(!) absolute favourites for a large Bb. Both low and high range speak far easier (and faster) than the PT/RT88 for me, also compared to the other big Perantucci PT/RT50. I also found (again: for me) that the 88 or 50 did not enable the full sound ...

I have/had the FMB, Gewa and Soundline in regular use. The FMB bags offer the best protection and are made of very strong material in a good quality at a very fair cost available here in Germany. But the Gewa and especially the Soundline bags are not far behind. An additional plus of the stiffer ...

Congrats to a very nice Tuba. I think I tested this particular instrument 3-4 months ago.

Good choice!

Best regards

Here's a Rudy F for sale, this store might also ship overseas:

In my opinion, having two decent players knowing their instruments and range is fun and sufficient for most setups required in a symphonic wind band. For some years we were two tuba players in our symphonic wind band, me playing a Besson 4v 17" comp and my colleague playing a Besson Eb 19". We could ...

Did you check the valve alignment? Misaligned valves can cause serious issues also on rotary instruments, especially having 6 of them. It should not just be "OK" but exactly on both opening markings to have the already small bore fully available. I have a small 4+2 rotary F and a really small 3+1 Eb ...

@Bloke, as for me I'd leave out the word "old". I'd be very happy to own the new 164GM I tested...with the advantage of less repairs and maintenance effort in the first 50 years of ownership :smilie8:

And yes, these instruments are somehow oldtimers referring to your analogy, but aren't we mostly ...
