tube-ing the Studio Pre like Timbrewolfes Triaxis advice

[Cheycaster]

I have a pristine Studio pre amp and it has all the original tubes in it. I also gave a Trixis and Timbrewolfes advise and in-depth tube comparisons really helped to "tone up" my Triaxis. I was wondering if there is any in-depth information on custom tubing the Studio preamps tube slots for more personalized tones like the suggestions Timbrewolf made for the Triaxis on this forum? Thanks!
