[GreenKeys] JAN 5670W Tubes

[Wayne Letourneau]

 According to my manual, 5670 is a Min. duo triode, ruggedized 2C51, heater
raised to 350ma, computer rated.  I had spent some time at Sperry Univac in
the 60's and I recall them being used in the early univac computers that
were at that time being built for the government. Each computer would fill
several semi trucks. Probably comparable to a later Apple II in performance

Several are also used in the AN/WRT-1 and AN/WRT-2 transmitters. Not likely
to be at the museum, though!
