Tube rolling with Hagerman Trumpet

Questions about tubes and gear that glows. FAQ

Has anyone done tube rolling with Hagerman Trumpet? What do you use? I am thinking of getting a Trumpet. Its web site says since the Trumpet is fully balanced design, the tubes should be matched. I am wondering how closely matched they need be? Should the matching be done for the two sides of the same tube? Or should it be the same side of two tubes? Do I need to match all four 12AX7 and four 12AU7?
