Since some year expeirence for older 12ax7 TII serie tube, PSVANE R&D for their new inside architecture 12ax7, 12au7, 12at7 and EL84 tubes and named for S Arit Seire, these tube keep the older tube feature but and it's more musical than older TII serie and have a better parameter than old serie,
12AU7-S is small middle U double triode tube with nine feet
