The area of heat that is the biggest problem are the filament connections.
We built a heatsink of sorts into the assembly to help out with the heat. So far it seems to be working fine.

Mr.KarstenThanks for you response !
BTW , I never understand why Russian manufacturer was build so powerful tube with so tiny tube pins ( except anode pin ) ! , with only 1,45 mm in diameter and only 10,5 mm long ,
maybe that was something intentionally with main design target to minimize temperature difference between joints of tube glass envelope ( bulb ) and metal pins just to avoid hard glass micro cracks( porosity ) and resulting vacuum loose , who knows ...

The reason it was done that way was because they were using an American tube socket design which was built for the 3C33, an American dual power triode. They doubled the plate area and made it into one tube instead a dual.
I have the Einsteins that use 4 of those 6c33 tubes each and it feels like having 2 little hibachi grills in that end of the listening room. I have visions of my electric meter spinning madly. But the sound!
