Someone in my tuba studio had the same problem...or so I think. He had something rattling. He brought it to a repair shop and they did something to the bell. Unfortunately it wasn't in the bell. Turns out there was something ringing or buzzing near the first valve slide. The solution: placing a blue rubber ball between the first valve slides and the adjacent slides. It worked.
