Sylvania 12JT6 12JT6A Vacuum Tube NOS NIB October 10 2023 These four Sylvania-MANUFACTURED 6U7G tubes

These four Sylvania-MANUFACTURED 6U7G tubes were tested on our Paul Hart-calibrated TV7/U for shorts

They were dead quiet when the preamp was muted and had excellent frequency response

I am playing them in my ArtSound 805 amplifiers with Badfinger's seminal "No Dice" album and they sound terrific

both with current readings of 34 and transconductance of 3520
