Instruments using a combination of high-speed valve dividers and dekatrons. With ten electrodes, which were used to provide a consistent-looking display on Groups (to enable divide-by-N operation - second photo), and display-only versions Variations included divide-by 12 tubes, tubes with seperate connections to all ten cathode Prescalers for a mechanical counter, count rates of 20-100Khz being possible. These tubes were often used in geiger and frequency counter applications, and as In a counter that advances the glow by three electrodes for every single input pulse. An external phase-shift network is used to provide the sequencing, resulting Sequentially phased pulses to these pins makes the glow discharge jump from one electrode Each cathode isĬonnected to one of three external pins, forming ten electrode groups. (Ericsson GC10B) has 30 cathodes arranged around a central anode disc. These 1950's tubes function both as counters and displays. Markings worn off - probably made by Valvo. Ten anode connections - sounds odd but this is the only way I could get this tube toĭisplay properly. Unlike nixies, this one seems to have a common cathode and 2"Ī 'pixie' tube, which lights a neon glow on one of ten plates behind a Giant National NL-8091 tube, digit height 1.5", tube dia. N.I.7, 1.5" STC GN-5 (sizes are bulb diameter). Three end-viewed nixies, 1" STC GN-4D, 1.3" Cintel 'Cathvisor' Plus East German 2" and 1.3" tubes (picture from Jorgen Lund-Nielsen),īurroughs B7971 2.5" alphanumeric tube, Okaya CD13 0.3" subminiature tube - as Huge 6" nixie Type CD47/GR414 RODAN Indicator Tube by Okaya Japan, With orange coating on glass to improve colour, Unusual ITT tube with sine, spiral, minusĪnd plus indicators, 'stretch NE-2' lamp used as first digit in 3½ digit display, Left to right : Standard tube (probably Mullard ZM1175), Mullard ZM1080, Group at yahoogroups - all the latest nixie news and design hints etc. Out this amazing glass Analogue to Digital converter! If counting glassware isn't clever enough for you, check Nixie tube power supply circuit For running More info on nixies and other display devices Here. Linksīuild a nixie clock Full construction info and I can provide custom-built nixie displays for TV/Film use - please email if interested. Still sometimes be seen in old electronic test equipment. ICs became available, the 7441 or 74141 TTL devices often being used as a driver, and can They were popular in the 1960s and early 70s when the first logic These neon-filled numeric displays, also known as 'numicators',Ĭonsist of an outer mesh anode, with ten cathodes (or 11/12 with decimal point/points) Counting & display tubes Tour : click picture below for previous
