12AU7 and 12AX7 long black plates vs short black plates. Any difference ?

That's why I tell my wife; "You'll get what you want and like it!"

Sabrina Carpenter's 2025 album cover for, "Man's Best Friend", which shows her on her knees with a man towering above her with a hand full of her hair, is iconic. Sign of the Times. 

It's like we are back in the early 80's again, without the feminism. Sabrina would have given Madonna a run for her money in those days. They have a lot in common, they are both real blondes and both are quite easy - if you know what I mean! - or at least that is their shtick. Not that there is anything wrong with that. Per David Byrne; same as it ever was.

Occasionally, to be funny, I utilize a heavy manly voice like Charlton Heston commanding well-heeled sheep and regale my wife with a "misogynistic quote of the day!" Resigned to the fact that she is female, she takes it sportingly well.

Whenever I do that, my wife gives me that 'Oh, really...' look, so I always finish with;

"If that’s all right with you..."

That's right, real men know how to read a room. 

Never let yourself get sucker punched. 

Hi we all talk and discuss the different subtle sometimes labelled subjective characteristics of various tubes and audio equipment in general? Aside from the obvious frequency response, noise and tube related std measures does anyone know of how these can be measured? For example subtlty, detail and naunce. Also “warmth and snap” and the so called “weight” tubes and sometimes electronic equipment add to music reproduction?

Thx

OP

in my humble opinion, I do notice that the long black plates have a more 3D sounding result with more vibrance and detail/ the short plates or may I add, the gray looking plates do not deliver the same sound or musical effect that i hear from the LONG plates.

I have both long and short and the black vs the gray. these are 12au7 and 12ax7 tubes of Tele, MULLARD and Sylvania manufacture. I notice that they are most sensitive when they are on my LTA preamp and the gain stage on my 845 audio note clones

this is just my observations and YMMV
