(1) Tested Ken Rad 6K6GT Tube Date Code 9-17 6K6 GT Tube Black Smoked Glass

(1) Tested Ken-Rad 6K6GT Tube. Black smoked glass with a bottom square foil getter. The 188 EIA code indicates that this tube was made byGE for Ken-Rad. 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.
