sorry the search engine has failed me and i just wanted to see if I could get some old advice again. Someone here recommended new tubes for my mesa .50 cal in the effect of Groove Tubes and JJ's. . . . . I just can't remember which ones where recommended as power tubes and which ones as preamp tubes, please help (FYI, a hard rock sound with 2x6L6 and 4x12ax7 thanks guys!!:bowdown
