A lot of the discussion here about multiplexing is in generalities. I use a number of Burroughs B5750 tubes (who have miraculously survived more than 30 years of clean-up attempts from the ball and chain :-)) and their documentation specifically states that this tube is designed for time share applications, and even provides data for increased anode currents at different duty cycles.
Since some tubes do not have that information, I would suspect they were not specifically designed with multiplexing in mind. This of course does not mean it would be bad for them I suppose.... Any of the tubes I multiplexed did not complain, although some did not like a 1-6 multiplex in the sense that there were brightness issues and some ghosting issues to be resolved. I have not had any noise issues from the tubes, but I use mostly small tubes that may be less susceptible.
