Mike, what's ya gonna do with all those tubes?

What else,I'm going to stuff them in my daughter's old bedroom where I have tons of other stuff stored.LOL.I've been using them in my many 6L6 and EL34 based amps as well as selling a quad here and there.

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.

Not only great sounding but long lasting! I got two quads from Jim in 2010 and have used the first quad for thousands of hours and they still test and sound new. The other quad has not been touched. Also picked up a box of 36 from a local guitar player a few years back for $100 Canadian (about $70 US). I think that should be a lifetime supply.
I too am loving the GL kt66 and intend to compare them to the 6P3S-E. But those are well over $200 US per quad. The 6P3S-E were $65 a quad fully tested from Jim and even cheaper untested by the box. That was a bargain that is unlikely to be equaled again in output tubes.
