I'm curious about slot-in valves, especially with respect to a Bach 50B. D tuning.

Doable I know, but practical (from a musical, not necessarily financial perspective)?

Pictures would be appreciated.

Hi Rod, here's one I had from a long time ago..second valve could be in D, Eb or bE and also allowed for single valve in F, E and Eb.











This used standard Bach tubing and valve - it worked well.

On my phone, so not sure if this will post, but check out the Bach Brass page on Facebook.

This 'slot valve' is added to the main tuning slide. Personally, I think this is a real bad plan, but it makes it an independent without forcing mods to original parts.

Cheers,

Gabe posted this inline modification on a Bach New York 50 that he saw recently. Looks pretty cool

For conversation purposes... is taking out a length of the tuning slide like that, "in theory", worse than taking out a length of the neckpipe?

Who knows?  To my knowledge, this guy in SF (can't remember his name) and alto bones with trill valves are the only ones to do it. I don't know that it has been experienced enough by enough people to have any working theory.

Billy Robinson?  In fact, that looks like Billy's 50.

Boosey & Hawkes used to make a main tuning slide based valve for their symphony tenor that Denis Wick designed... not the best piece of kit ever, but it sort of worked.
