Color TVsDomesticSince 1959, the Emerald-203 television receiver for color images has been produced by the Moscow Television Plant. The television receiver "Izumrud-203" is a floor-standing projection television for individual use for receiving color and black-and-white television broadcasts. The TV is made in the form of a console structure, in a beautiful case, veneered with valuable species of wood. The color image is formed by a system of mirrors and three projection kinescopes that focus the television image on a special screen located in the cover of the case, which opens and installs vertically when watching television. The visible size of the image is 350x460 mm. The TV works in any of the 12 channels of the MW range. Sensitivity 30 μV. The speaker system consists of three loudspeakers, one woofer and two midrange located on the sides of the case. The range of reproducible frequencies is 50 ... 12000 Hz. The TV uses 36 lamps and 22 diodes. Maximum output power 6 W. Power consumption 400 watts. When viewing black and white television broadcasts, one projection kinescope or all three could work, while it was possible to obtain image shades. The main control knobs are located at the top of the case and are accessible by opening the cover with the screen. The control knobs for the alignment unit are located on a vertical panel covered by a hinged cover. Auxiliary control knobs are located at the bottom of the case, which has a special hinged cover. In a small batch of TVs, high-quality sound is provided by four loudspeakers (4GD-1 - 2 pcs. And 1GD-9 - 2 pcs.). The design and layout of the TV chassis, as well as optical systems, lamps, control knobs, technical characteristics are the same with the Emerald-201 projection color TV. The screen of the Emerald-203 TV is smaller than that of the Emerald-201 model, therefore, the brightness of the screen glow here is greater than in the basic TV. Engineers developers: V.M.
