Greetings,

I'm working on laying out the valve circuits for an Eb tuba I'm building. I'm using the valve section from a Conn 12J BBb tuba, but several of the crooks are cracked and/or have holes in them. If anyone has any of these crooks (or same bore size from a different horn), please let me know. I'd like some that I don't have to mess with patching. The crooks I most need are the top crooks for the first and third valve slides.

Here's a photo of my mock-up circuits, dry fitted at the moment.



Thanks!

Hmm... I'll have to mess with it tomorrow. It showed up when I was writing it, but maybe because I was logged in to Google and it was just showing up for me. Thanks for the tips on the cracks. If I can't find a couple crooks, the ones I have are salvageable, I was just hoping to find a few if anyone has some. Thanks bloke!

Is the picture showing up now?

Yep. Looks nice!
Good luck with the project.
