Hello everyone! As stated in the title, I'm looking for some inner/outer tubing for a frankentuba project. A complete 1st valve slide assembly would be ideal. Email me at tylerferris1213@gmail.com if you have something!

Your repair tech should be able to order those parts. Mine ordered 2 assembly's for me a few years back for a 5th valve conversion on my YCB-661 (same bore). I think they were about $70/each?
