Particularly with tubas where the "1st" valve is the first valve past the mouthpipe, it is not uncommon for the 1st valve to stick
- Junk from the mouthpipe is dumped into this valve.
- Often, tubas are picked up by 1st valve slide parts, putting pressure on a 1st valve casing.
Any really good repair folk can fix this.
