Description: This matched pair new old stock-testing GE 6SN7GTB vacuum tubes was tested on our Jackson 648. Tubes measured: Tube One: 91 / 102 (91% / 102% 6SN7GTB and GE dot codes on glass; unbranded base)Tube Two: 97 / 99 (97% / 99% 6SN7GTB and GE dot codes and K on glass; unbranded base) On the Jackson 648 good range is from 70-130.Listened to pair in our Alan Eaton amplifier; are dead quiet when the amps are muted; and have excellent frequency response, sound-staging, presence and dynamics (see pics). Pair have black wing plates, short bottles and bases and a single side horseshoe double bar getter. Tight on bases with no debris or rattling sounds. These could possibly be manufactured for GE by Sylvania or Hytron. Only guessing Hytron as I have another tube just like it branded by Hytron.
