Lamp Plant oscilloscope UNITRA "Zelos" HISTORY:
Lamp Plant oscilloscope-Zelos, Zelos Unitra then in New Iwiczna near Warsaw (near Piaseczno) was a manufacturer of picture tube (for monochrome TV), radar and oscilloscope. Zakład ten znajdował się przy ul. This plant was located at. Puławskiej, Puławska, practically adjacent to electron Establishments Lamina.
Zelos was created in 1957 through the separation section of the lamp oscilloscope Electric Lamp Factory of them. R. Luksemburg przy ul. R. Luxemburg Street. Karolkowej. Karolkowa.
The choice of location in Iwiczna was due, inter alia, that the Department required a lot of space on the lines. In the first years were manufactured 14-inch tubes (35MK1), used among other things on TV, "Belvedere" and "Turquoise" and produced oscilloscope tubes were manufactured under license from the Soviet (eg 8ŁO30, 18ŁM35). In later years (60s) for the production came CRT 17 - inch AW43-80, developed at the Industrial Research Institute of Electronics, as an equivalent CRT Philips. For example, we can give the picture tubes used in TV sets such as "Amethyst" - Type A50-140W, "Vela" - Type A31-310W. Perhaps the greatest diagonal dimension of the produced cathode was 61 cm (tube A61-140W).
In 1974. Edward Gierek, the U.S. signed an agreement under which the plant was producing Piaseczno color picture tubes. These tubes were manufactured under license from RCA. In 1976 some of the staff went to Zelosu Polkoloru . They were, after all, good specialists monochrome television, a color picture tubes have a technology similar to the monochrome CRT. Manufacture of lamps oscilloscope was transferred to the Department of Professional Lamp, subordinate Polkolorowi. Professional Lamp Plant had at least two locations: one at ul.Bielańskiej 10 in Warsaw, the second in Piaseczno (it is not known whether the area or the area Polkoloru Zelosu). Not entirely reliable information they say on the seat at.
In the 80s, when she began the computerization of the country (Computer Junior 800) Zelos A31-tube produced a green color 310G Electrical świecenia.Parametry the tube were similar to the picture tube A31-310W. Monitor to the computer system was based on part of the TV "Neptune 150" (eliminating IF path and head). plant collapsed, and the buildings were demolished around 1998.
