Vacuum Tube Quiz
|
||||
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 magazine. 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. The VHF and UHF aeronautical band radios also contained vacuum tubes, but we didn't service them. Don H. (from my radar shop), I know you'll take this challenge; 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.
See answers below. Popular Electronics published many quizzes over the years (as did a few other magazines to a lesser extent) - some really simple and others not so simple. Robert P. Balin created many of the quizzes. This is a listing of all I have posted thus far.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
