Bicycle_man the 6080 is a dual triode, but both units are used per channel !
So for a stereo pair, two 6080 tubes are required; one per channel so cross chalk is not an issue.
It uses EL34 as CCS to regulate the plate voltage, Kool.
Since you sound serious, give me your mailing address and
I'll send you a copy of this article/schematic.
It's by Mr. Pete Millett, I have no idea who he is, but sounds to me, he really know his tube stuff !!! and is probably the most knowledgeable tube guy I have ever come across.
But as I warned, before, EXTREMELY microphonic, precautions
must be implemented, like floating sockets or boards, but the pain is well worth it.
