What reverb tank does a Mark II B Head take?

[Orbis_Mortis]

I need a reverb tank for my Mark II B head. I was wondering which one it is. I heard it may be the accutronics 9AB2A1B but I can't find any conformation on that. Does anybody know?

Best to call Mesa and ask. They will probably have it in stock too.
