OB2 SPICE model

To be able to simulate a stabilized supply, I need an OB2 SPICE model. Or a model for another voltage regulator tube I can adapt. I googled but didn't find anything.

If such a model doesn't exist, what would be the right way to go to make one? Modify a diode, or start with some voltage or current source? For now, I use a diode with a reverse breakdown voltage of 108V, but I would likely have a better model for that tube.

Can someone share such a model, or know where I can find one?
