Raytheon Numerical Indicator Tubes and Data Display Devices

Wax nostalgic about and learn from the history of early electronics. See articles from Electronics, published 1930 - 1988. All copyrights hereby acknowledged.

Before there were side-view neon numerical indicator vacuum tubes there were top-view neon numerical indicator vacuum tubes. Nixie tubes and pixie tubes were featured in "Readouts and Counter Tubes" in the October 1959 issue of Electronics World magazine. At the time, most were top-view designs whose size was restricted by the diameter of the tube (typically about 0.8"). Switching to a side-view format did not enable the overall width to increase much, but the aspect ratio permitted taller displays with characters that appear as normally seen (rather than being squashed in height). This advertisement in a 1965 issue of Electronics magazine for numerical indicator tubes from Raytheon were likely some of the first side-view models available from any manufacturer.

you won't look down

at the New Raytheon Side-View

Numerical Indicator Tubes

Because of their unusual design, the new Raytheon digital, in-line miniature indicator tubes offer several important advantages over conventional top-viewing indicators. For one thing, their unit cost is lower. They require less mounting depth, allow close horizontal spacing and display large characters for the available viewing area.

These new Raytheon Side-View Numerical Indicator Tubes also feature conventional non-segmented characters for maximum readability, low power consumption, exceptional reliability and ultra-long life. Raytheon Side-View Numerical Indicator Tubes are available with numerals 0 to 9, characters + and -. Types with custom characters can also be provided. A mating Raytheon tube socket is available at low cost.

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 tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
