I have used 12AX7's that only read 60 per cent in V1 and V2 and the owners are thrilled with the sound they get.) V3 isn't as critical, but I still put a good tube in it anyway...

Thank you! Now that is what I have been looking for. I know that there is going to be a certain amount of experimentation no matter what, but up to this point I really have had no clue where to start. So reading this really rocks!

I have all GE 12Ax7's (1964 date codes) in my DSL401 with Canadian made RCA Black Plate EL84's. What a monster! Total difference in tonal qualities versus the stock OE tubes.
I wish I could bring some of my tubes and my tester up to where you live and we could have some fun dialing in your TSL122. However, you know if you have a question you can contact me here or by PM.

What kind of differences in tone qualities between the different tubes you have tried?

That being the case I would like to know more about how preamp tubes effect my sound.
I play mainly classic rock ranging from AC/DC to Def Leppard. Clearly I love distorted guitar tone, but I also love the way my TSL122 sounds on the clean channel. So...
What I am hoping for is feedback from you more experienced members of the forum regarding such topics as: How will different tubes change my sound to better suit my style of playing? What tonal qualities do different preamp tubes have? What is a good starting point for finding the right tubes for me? Can I "mix-and-match" preamp tubes? How long do preamp tubes last? How often should I replace them?
Please, do share your thoughts on this subject. I am eager to know what your experiences have been. Thanks in advance for your responses!

I guess I am hoping someone out there with more experience will just say... "So you're playing this guitar, this amp, and you like this style of music.. Why don't you try this... (such-n-such combination of pre-amp)" Then I have, to my mind, a good starting point for experimentation.
