If you had a dozen pairs of classic vintage ubes in your closet

Are you asking why people don't replace worn out tubes? Or are you asking why people don't feel compelled to audition tubes they own, even when the tubes in use are fine?

The usual is to try them even if satisfied with the currently installed ones. You never know.
That's what i did when had plenty of nos tubes, now most of them are sold and couldn't be happier.

Why would I resist? Who would I be resisting anyway? Myself? Only if I was a neurotic mess would such a thing even cross my mind. Instead, being of sound mind, I would either get a few out, try them, and keep the best ones, or be happy to have spares, go and do something productive, and forget about it. In fact I don't even have to guess, that is what I have actually done. Not a dozen, they are so far out of my mind I couldn't even tell you how many or what they are. Seriously. Or how many hours are on them.

This kind of question has me imagining a guy looking at his belly button in the middle of the night wondering how much lint might be in there. All night long, wondering. Could just go fishing, but can't stop wondering. Maybe go on-line, ask how anyone ever manages to do anything but wonder about their belly-button lint..... I mean really, how do you resist?

why not? if you have them

i would also use spell check and re-read what i am posting, if for no other reason than to be considerate of others

@jjss49, perhaps you should consider that English is not everyone’s first language.
