Get a Cit. 5 and see if they will hold up. Maybe tweaking the "idle" current would be needed.

Aren't these tubes 19watt?
The 6П3C-E (6p3s-e) is supposed to be much like a 7581, unlike the 6П3C.
We must be careful about Russian types, as the suffixes are very significant. The 6П14П is, at best, a mediocre EL84 equivalent. OTOH the 6П14П-EB, AKA EL84M, is a quite nice and very tough 7189 equivalent.

I'd be inclined to consider the 6П3C-E to be much closer to 5881 than a 7581. A translated data sheet calls out anode dissipation rating @ 20.5W while the 7581 is 30W and the 7581A is 35 W. I'm sure the 6П3C-E ratings are conservative because they're based on a 5,000 hr nominal life. I've run them @ 25W on the anode and they don't red plate or show other signs of distress.

You are actually correct.The 6N3C-E is often sold as a 6L6gc,mainly because of its mil-spec ability to handle the 500v of the 6L6gc,even tho it dissipates roughly the same wattage as a 6L6GB or 5881.In other words,they do have a lower dissipation rate than a 6L6gc but,they can still handle the voltage and current of the 6L6gc.
