Made by National Union for WE. Nothing printed on them that would suggest a date of manufacture, but the double D getters make me think that they're probably from the 50's. I have NU 807s from the mid 40s war era that have D getters, but they're on opposite sides. These essentially are WE's 807 - a transmitting 6L6G, but more stoutly made. Electrically same as 807 but the heater current is 1.6A vs. .9A for the 807. Not quite as well matched as I like but suitable for single ended designs or cathode biased: 55.6mA and 47.3mA @ 469V. Clean as can be. $275 PP gift shipped CONUS.
Thanks for looking.
cheers,
