I used the Genelex reissue 12ax7 in a preamp and phono preamp, and they worked fine. Good enough. Still better than SS. No, not quite the equal of fine NOS, but better than Sovtek/EI, which sounds strident in my gear. I got tired of obsessing about and paying for NOS tubes. This way, I can also use tube amplification for the tv, with no worries - which sounds great.
