Yeah, but let's be honest with each other, Kev, they're not nearly as
good as later model, NOS US & European made 6V6's. They're not really
as good even as earlier 6V6's, I've tried 'em (more than one set, IMA)
in an old Hammond M3 and they didn't work right. They're a knockoff,
albeit not a great one, of a 1940's RCA, as are a number of other
Russian tubes, I don't think that Russian 6SN7's looking so similar to
1940's RCA's is any coincidence.
Sure, you can run 6V6's at nutty voltages by limiting screen current
or voltage, and AAMOF, if I ever find time, I'd like to try 'em with
some kind of current regulator (as opposed to a voltage regulator)
just to see how well that works.
But I bet if you could scrape the black shit from
inside a Sovtek 6V6, even with the higher screen resistor you suggest,
you'd see the screen glowing red as a beet with any kind of decent
size signal, even in a DR, let alone a Super or Twin.
