Well. I have some general Spice models for some of the types you mention.
You can also find more Spice models for tubes at:

Unfortunately I haven't tried any of these models yet.

I have found some links about Spice simulation and models for vacuum tubes, maybe you will find it interesting.

Thank you for your help
Do you think that we can make some relevant AC simulation with those model. For example for
distorsion measure we don't have the noise model.
Anyway it is a good start for DC analysis: operating point identification and input sensitivity with respect to the input driver choice.
Did you check yourself some test bench with 845 or 211 SE?
Best Regards

Yes, you can do some AC analysis with these models, although you can't do any noise simulation since these models doesn't describe noise in any way(I think).
Distorsion analysis will also be a problem, my experience is that even the characteristic tube distorsion will not be shown when doing AC analysis.
