There are still a lot of vacuum tube guys out there who might remember enough about them to score well on this quiz that appeared in the February 1961 edition of Popular Electronics. My own exposure was mainly with airport surveillance and precision approach radars while in the USAF. We didn't have a lot of the fancy special purpose tubes shown here, but I was able to guess correctly on some of them based on how the tube is constructed and the response curves. Still, I'm embarrassed to tell you my overall score. Don, I know you'll do this; tell me your score and I'll tell you mine.
