Black-and-white television receiver `` Izumrud-205 ''.
Black and white televisionsDomesticThe Emerald-205 black-and-white television receiver has been producing the Novosibirsk Electrosignal Plant since the 1st quarter of 1971. The unified TV set "Izumrud-205" (ULT-61-II-3/4) is decorated in a wooden case, finished with precious woods and polystyrene in soothing shades. The TV was produced in table and floor versions. The TV works on any of the 12 channels of the MW range, and when installing SKD-1, and in the UHF range. Models with the `` D '' index already have the ability to work in the UHF range. On the right wall of the case, behind the grill, there are two loudspeakers of types 3GD-38E and 2GD-36. The back of the TV is closed by a plastic wall with holes. The model uses printed wiring. The main settings are located on the right of the front panel: the UHF range scale, knobs for the UHF channel selector, volume, brightness, contrast, channel selector, buttons for turning the network on and off, buttons for switching the UHF / UHF. The APCG system makes the transition from one program to another without adjustments. The AFC and F system increases the stability of the image in case of interference and power fluctuations. The AGC system creates reception stability at different signal levels. The stabilization of the image size is also automatically adjusted when the voltage in the mains or lamp mode changes. The TV allows you to change the brightness or volume with a wired remote control, listen to sound on headphones, with the speakers turned off in the speakers, and also record it on a tape recorder. The technical characteristics of the TV are similar to those of the unified class 2 black and white TVs. The Emerald-206 TV (ULT-61-II-3/4) produced since 1973, in addition to the external design for all other characteristics, electrical circuit and design, is similar to the Emerald-205 TV.
