Having the power bills to prove it, I have some experience with 833s as ESL direct-drivers. Why do you say that they are inherently non-linear? I do think that they need a very high primary impedance to work properly, and it's hard, really hard, to make a decent monster high-voltage OPT with a very high input Z. Maybe that's what you're thinking. The published plate curves show very little in the negative grid bias region, devoting more space to the positive grid regions, since this was an RF tube after all. I charted the 833's lower current, higher voltage behavior, and it seems quite linear. It measures well too.
