A Spheroid v2 tube will work with a Spheroid v3 base - the tube threading to the base is the same. I just bought a v3 base to use with my v2 tube and v2 bell (and I love it).
I don't have a Spheroid v3 tube or bell but from what I've read on the Tips and Tricks thread you should be able to push the bell up from the bottom to remove it from the tube.
Thanks for the quick response. I feel like such a dolt. I've got both the v2 and the v3, so couldn't tried switching them myself! Oh well...
Yes I know about pushing the bell from the bottom (from the inside), I do that with the Heron - which I can get a decent grip on. But the Spheroid is a lot trickier - at least for me.
Now - to find someone with a v2 tube and bell that really wants a v3 tube and bell
