Used lots of Russian valves and found them to be good generally.
Gettering on some is patchy, often its at the bottom rather than the top.
I have some Russian ECH81s that seem to have practically none at all but they are fine.
If they are soft you can usually see the milkiness if you look at them with a light behind. The filament will usually burn out in a couple of minutes too.
