The fingering chart on the "tips" page is not an entirely exhaustive list, though. For instance, on BBb tuba, the "12" combination used by some players instead of open for the F in the staff isn't included...
Here's everythin you need to know to figure out your own chart...
Open - fundamental of the instrument (e.g. pedal Bb for BBb tuba, etc.)
2nd - one half step below fundamental (e.g. pedal A for BBb tuba)
1st - one whole step below fundamental
3rd - a minor third below fundamental (same as 1st and 2nd, but a touch flatter)
4th - a perfect fourth below fundamental
5th - either a larger-than-normal whole step or a major third, depending on your system
Harmonic series on a BBb tuba goes as follows (i.e., notes you can get with an open fingering):
pedal Bb;
low Bb, F just below the staff;
Bb in the staff, D in the staff (a bit flat), F in the staff (sometimes a bit sharp), Ab on the top of the staff (quite flat);
Bb above the staff, C above the staff, D above the staff (a bit flat), Eb above the staff (about a quarter-tone sharp), F above the staff, Gb above the staff (about a quarter-tone sharp), Ab above the staff (quite flat), A-natural above the staff;
Bb several leger lines above the staff... and so forth.
Transpose this harmonic series down a half step, and you have all of the notes you can get with second finger. Transpose down a whole step, and you have all of the notes that you can get with first finger.
Keep in mind that the more fingers you add, the sharper the note gets. Also keep in mind that just about anything involving fourth valve is going to be a bit sharp.
Hope this helps more than it confuses.
