This is for the tube rollers out there.
I got my torii mk3 a couple years ago. It came with JJEL34s and JJ6922s. Something has bee off lately, so I decided to order some new tubes. Got E Harmonix 6922s and JJE34L's. (not EL34)
I didn't know they existed or there was a difference. I laughed thinking some worker had too much Russian Standard Vodka, went to work, and transposed the letters in the machine that paints the numbers on the tubes. E34L vs EL34.
Anyway, there was a considerable difference. The torii was louder and sounded "different". so I searched and learned that the E34L is a EL34 that burns a little brighter (and maybe shorter?)... which lines up with my perception of more power.
I still had the boxes from the old tubes.. the "matched quad" numbers were 24/4.6 and the new E34Ls are 38/5.8. I don't know tube testing well, but if these numbers mean how many electrons are passed for a given input, then the new tubes are "stronger".
Anyway, I'm getting used to the new sound. Again, it's different. Maybe I got more on the high and low end, but lost something in the middle. It's overall better than it was, but seems like the quality in sound just shifted around somewhat. know what I mean?
I've seen other talk about various el34's and 6ca7's... technically, they are the same tube.. same specs. the E34L is different.
Does anyone else have thoughts/experience with E34L's vs EL34's?
