Vacuum Tube Quiz
February 1961 Popular Electronics

February 1961 Popular Electronics [Table of Contents]People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Popular Electronics was published from October 1954 through April 1985. As time permits, I will be glad to scan articles for you. All copyrights (if any) are hereby acknowledged.

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.
