 May 1958 Radio & TV News [Table of Contents] Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

If you happen to be a retired television repairman from the era of analog broadcast and cathode ray tube (CRT) displays, or if you have studiously read the many articles I have posted from vintage electronics magazines about TV, then you will probably breeze right through this themed crossword puzzle from a 1958 issue of Radio & TV News. I have to admit to having done poorly myself, even after having been the one who posted all that stuff. Just having a general knowledge of electronics doesn't help much here since all the clues and words are very specific to television circuits. Still, it's worth the challenge and if nothing else you'll learn a little more about old time television- it really was a quite ingenious scheme for cramming a lot of information into a relatively small bandwidth, especially for color TV.

TV Circuits Puzzle

By John A. Comstock

(Solution at bottom)

 Across 1. The purpose of the video _____ is to increase the amplitude of the video signal frequencies. 6. A type of TV antenna in which the various elements are in a vertical plane and spread out fan-wise from a lower junction. 8. The first series of circuits that receives the incoming signal immediately after the antenna. 9. In a color TV receiver, it is the function of the sub-carrier oscillator to generate the _____ subcarrier frequency. 12. A regulator type of circuit that maintains the output of a TV receiver constant irrespective of a fluctuating input signal. 13. The _____ amplifier in a TV receiver enlarges amplitudes of sound frequencies. 14. In this circuit, the incoming signal is combined with a local oscillator signal to produce an i.f. signal. 16. The matrix amplifier in a color TV set is a combination of voltage divider _____ works and amplifier stages. 17.
