Question Where did these EL84 numbers come from?

I was poking around the other day and found this article-
http://www.tubecad.com/september99/page11.html
wherein it is stated that the EL84 needs 300 to 400V on its plate and 16V of drive.

When I look up the tube data I find the recommendation of 250V on the plate and other sources indicated that 10V of drive voltage is what is required.

What am I missing?

Looks like he is talking specifically about the Russian versions and not NOS. Here is some data I found using Wayback:

Aha! I was looking at various data sheets for the EL84 but he does mention Russian so I should have been looking there.

Thanks for the post!
