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.
Vacuum Tube Quiz
By Robert P. Balin
Glancing at a tube's symbol or one of
its constructional features should remind you of the graph of its
characteristic curves or its outward appearance or application.
Try to identify the numbered items at left, below, with the corresponding
lettered items at right. Answers are at the bottom.

Popular Electronics published many quizzes over the years
- some really simple and others not so simple. Robert Balin created many of the quizzes.
