Longer Third Valve Slide to Correct Intonation Issue?

[Roger Lewis]

Hey! Stuff happens, okay? I found the issue and have free longer slides if there is an issue with individual horns. I've given away a number of these slides to help people out.

Just trying to correct a flaw from 15 years ago.

Looking for an update?

Long story short, Miraphone is going to build me a new third valve slide that is two inches longer (overall). Explanation for the intonation issue is that this is a tendency in larger bore horns. Actually, here's their response word for word:

"All valve slide lengths on our tubas are designed to be on the short side in order to give players some wiggle space for flat notes. The recommended fingerings are always to use as few valves as possible, therefore we recommend using the 3rd valve for the D instead of the 1-2 combination. For D-flat 2-3 is the only option, of course. The slides of 2nd and 3rd valve should be pulled enough to make the D-flat manageable, but not too far to make the G-flat to low. As always, the final adjustments of valve slides is a compromise between the notes on the horns with sharp tendencies and the others that tend to be flat. The 191 is a fairly large bore horn, which makes intonation a bit more challenging, of course. The 186 model series, for example, is a 4/4 bore tuba and intonation is much more solid on these moderately big horns."

Thanks for the offer, Roger, but I have the main slide only out an inch. Nothing wrong other than these two notes.
