Conn Slide Compatibility

Post by Matt K »

As with the King thread, I find this type of information to be extremely useful. Hyperbolica contributed the following:
3 Conn tenons...

The old 485/500 sizes can swap slides (6H,10H,48H/24H,12H,4H)

The old 522 slides fit each other (50H, 78H, 79H)

The new 525 and all 547/562 all fit (8H, 88H, 52H, 6XH, 7XH,11XH, SLSL, etc. )
I can update this with more information if you have something to contribute. Maybe I'll merge this with the king and include others as time progresses.

These are correct for the most part. There will be some exceptions on a case by case basis.
6H (K series)
Elkhart 60s' 6H bell/5H slide
78H (K series)
8H (N series bell w/ modern slide)
88HN
71H (dependant valves)
72H bell section (half moon)
35H alto (K series)

My 40s 32H is is compatible with my 20s 78H, which makes sense. My 40s 30H is not compatible with my 20s 24H (the 30H receiver is a bit bigger), but I'm not sure whether the 24H is identical to newer 485/500 slides. IIRC, this 24H was close enough to be compatible with--but not identical to--the receiver on a 50's 24H I had.

Conn 30H (1936) and Conn 6H (1960s) are incompatible.

Greenhoe and Besson slides fit the 88H, 62H and the 7xH as much as I tried out

Caveat: The SLxxxx slides are shorter than the 7xh slides. By "compatibility" I think we are meaning the tenon fits, not necessarily that the slide is playable and in tune.

I posted this info in a different thread last year, but it's worth reiterating here.

Yamaha 641/643 bells (red brass) and slides (.551 bore, nickel silver outers and crook) are interchangeable with Conn 8H or 88H bells and slides.

IME the 641/643 bells are typically on the heavier side, so if you have a 1950's 8H or 88H with the typical lighter bell and red brass outers, adding a 641 or 643 to the mix will give you four distinct permutations of sound and blow for very little money.

With the exception of the bore sizes, the slide blueprints are practically identical, so no serious issues with intonation.

Getzen s have Conn slide connectors for tenors. The Edwards tenor slide is also interchangeable. The Getzen 547, 562 slides are also interchangeable. This interchangeably is very helpful when configuring a horn for a particular playing situation. The same can be said for lead pipe interchangeability .

I just put a Coprion bell - is that 18H? - on a 1936 4H slide and it seems to work really well. Anybody else try this?

Thanks

I have the 18h Coprion bell with a 48h constellation slide, works like a charm. I’ve heard of people doing it with the 6h slide as well.

Can an 8H/88H slide be used on a Courtois 420?

Pretty sure the 420 has a Bach 42 style receiver (so, no).

So a 74H slide fits a 78H/79H bell. Will a 76H or 50H slide fit a 78H/79H bell?

A 50H slide will mate up with a 78H and 79H bell, but it is shorter and narrower, so it will raise the pitch, making it unusable.
UPDATED- see below.

Cool! I would just need the receiver parts since the obes for 78H/79H aren't made anymore.

I just re-checked the 50H slide with the 78 and 79 bells, and they do fit together, just as I remembered.
However, what I remembered wrong is the tuning - despite the slide being shorter and narrower, I could play an in-tune Bb in first position, with the tuning slide pulled out about an inch.
What does not work is the 78 or 79 slide with the 50H bell - it plays flat even with the tuning slide all the way in.
Go figure.
And here is a pic of all 3, from top-bottom: 50H; 79H; 78H.

Another finding...
The (late - Brass bell 0.500") 18H slide and the 4H slide, will interchange...
BUT - the 4H slide is about 12mm longer than the 18H is.

So, if I have read the comments here, a Greenhoe dual bore bass slide (.562-576?) would, by all standards, fit my Conn 62H prototype?

I could really use an extra slide.

Yes, though I think the Conns are narrower than Greenhoe-made slides.

As far as I can tell, the Conn 4H and 44H have the same bore and at about the same time. Does anyone know if a 4H slide will work with a 44H bell?

So, does the 5H fall into the same category as the other 485/500 bores horns?

I am curious, will the 100H slide work on a 1950s 6H or 10H ?

I'm looking a slide for my Conn 8H bell.
It is difficult to find a used original. Recommend something from other brands, please

I have an 8h original Elkhart slide (50s) I'm not using. The slide action is not stellar, but its a solid starting point.

Getzen large-bore (0.547in = 13.9mm) slides are compatible with Conn 8H and 88H bells.

no, they are not compatible, with the two i tried at least. the 44H slide connector is larger, and the threads may be different too. the intonation is also slightly off one way or another, though i can't remember which.

Two additional comments. 78/79h slides fit tenons but the braces are in different places on the bell and slide sections. Its hard to use 78h slide on 79h bell because the left grip is very small. 79h slide on 78h bell stretchez out your grip.

Second, 83h slide fits other Conn large bores, but it is also the longer 72h length of slide. It is longer than the 88h, 62h and SLxxxx slides.

Getzen (not Edwards) should fit. Also, some early Yamahas fit as well - not sure about their current offerings. Pretty sure the newer Conns have the same fit.

Tested a 112h slide with a 72h bell. It fits, including the threads.The tuning slide does pull out enough to play in tune (a=440) - but there is not much length left. Sounds different than the 72h slide, and you lose the benefits of the longer slide.
As expected the 112h bell with 72h slide does not work, far too low.
