tuning slides of yorkbrunner

I assume those other slides are just valve slides... there is probably only one main tuning slide. The main tuning slide is the one that comes out the bottom of the 4th piston. Those other slides are probably for the 3rd and 4th valves.

The Yorkbrunner's main tuning slide is at the bottom of the horn directly in front of the bottom bow. There is only one. It is the slide you see on the bottom of the horn that is connected with the 5th valve rotor and is closest to the top in the picture.

Both the third and fourth valves have movable slides at the top and bottom of the horn, meaning two slides each, which are the other two slides you see pointing down at the bottom of the horn. These slides are connected with the two at the top, which also move.

The first valve slide and second valve (hidden from view but on the front of the horn) slide only move in one spot, as does the fifth valve slide, which is on the other side of the horn and is not visible on the front-side view.

So, starting at the left of the picture on the top going down is...

Tuning
Third valve
Fourth valve

And at the right of the picture going down is...

First valve
Third valve
Fourth valve

Lots of slide pulling and spinning is necessary when playing the Yorkbrunner, and it's a good thing it has so many slides available. When cleaning it, one must keep track of eight total slides when they are all taken out!

I hope this has been helpful.

On my Yorkbrunner, I used to adjust slightly with the first slide on a few things, but not all that much. However, I did adjust with the fourth slide (the top) quite a bit when having to use 2-4 for the low Db's. But for the most part, that Yorkbrunner played itself.

I have found that my current CC, a MW 2165, has very similar playing characteristics and I pull the same slides for the same notes.

For example - 4th valve.

You find that to make D below the staff in tune the 4th valve slide needs to be out 1 1/2 inches. To make the Db in tune, the 4th valve needs to be out a total of 2 1/2 inches.

So, you could pull the top 4th valve slide out 1 1/2 inches and keep it there most of the time... pulling out one inch more for Db and pushing back in an inch to go back to D.

OR, you can pull the bottom 4th valve slide out 1 1/2 inches and keep the top slide all the way in. You pull the top slide out 1 inch for Db and push it all the way down to go back to D.

You should find the second way better.

I've seen Gene adjust the fourth-valve slide extensively when playing in the very low register, on the CSO York itself. And I've seen Jacobs with his hand on the third slide of that instrument.

On my Holton, which is a similar design, I use the bottom slides for pulling and dumping moisture and the upper slides for adjusting intonation. That way, the slides I pull and dump can just be pushed home without worrying about setting them in the right place.

I don't adjust the third and fourth slides as I play the Holton. Not that I play in tune.
