So recently, there has been a lot of rattling when i play. Here are the notes in which the rattling occurs:
1st valve: Eb (major rattle) and Ab (faint rattle).
2nd valve: E (major rattle) and A (faint rattle).
3rd valve: D (major rattle)
4th valve: C (faint rattle)
So as you can see, I'm mainly having problems with notes in the staff, especially in the partal of F with valves pressed down. It is really only bad on the 1st and 2nd vavles, since those are the notes I play often (Don't use 3rd valve for D). I've tried flipping the springs in these valves, and that doesn't work.
My horn I use is a 1977 Besson Compensating New Standard, and a gold-plated Schilke 51D Mouthpiece.
Does anybody have any ideas on why this is occuring and how to fix it?
EDIT: I've found the problem. One of my spit valves was loose, causing an air leak which I mistook to be rattling from the valves. The screw on it protrudes much farther than that on the other spit valve on my horn. (The problem one is the main tuning slide, the only other one is the first valve). Is there a way to fix this issue, so this problem doesn't happen anymore?
