At some point someone had referenced 6v6, 6l6, etc. so I was addressing the tubes as a group. My point was simply that the internal connection is to cathode, which isn't necessarily ground. All that said, there were a handful of cathode-biased 6L6 amps, including early Fender Twins. I've never gotten to open one up; I've just seen the schematics.
don’t recall anyone mentioning 6V6s but thanks anyway!…
How does it sound? I love the old Gibson amps but haven't played through many Epis.
trying to find a schematic but searches send me to Gibson RV stuff…..rebranding?..hmmm…


Is this largely because pharmacists generally are not "chemists" as in years ago when they had to make much of what they dispensed--but it's still important (but useless day to day), to know how meds are created?
