The open bugle of a Dynasty GG I had here a while back measured roughly 22.5 feet.
The open bugle of a BBb tuba is roughly 18 feet.
The tuning circuits for a BBb tuba are roughly:
BBb
1st valve = 26.66"
2nd valve = 12.66"
3rd valve = 39.32"
4th valve = 69.32"
Take those BBb measurements times 1.25 to get your rough lengths for GG tuning circuits.
