(1) TestedBalanced RCA 6SN7GTB Tube. Balanced mutual conductance (Gm) with a thin base, black angled plates, top halo O ring getter and sawtooth mica spacers. Date Code NB (February of 1963). We prefer the versatility and precision of Hickok TV-10 military testers and use them almost exclusively except in rare instances when pinout/socket compatibility is not possible.
