Black and white televisionsDomesticSince 1960, the Rubin-104 black-and-white television receiver has been produced by the Moscow Television Plant. Model constructor V.M. Khakharev. Network TV `` Rubin-104 '' was produced during 1960 in a small experimental series. According to some reports, 1,300 TVs were produced in a tabletop design and 400 in a floor-standing one. The TV belongs to the second consumer class. It is assembled on a 43LK5B CRT with an electron beam deflection angle of 110 degrees. The model uses AGC and APCG, and therefore there is no local oscillator adjustment knob. Stabilization of horizontal line size is applied, vertical size stabilization is introduced. The overwhelming majority of elements are located on printed circuit boards. The TV works in standard 12 channels. Its 100 μV image channel sensitivity allows it to receive studios within a radius of up to 80 km. The sensitivity for the sound channel is 50 µV, for the FM reception of 30 µV. The speaker system consists of two one-watt speakers and is located at the bottom of the front of the TV. The range of reproducible sound frequencies is 80 ... 8000 Hz. Thanks to the use of small-sized parts and a new picture tube, the TV has a small size, weight and power consumption of 100 watts. Dimensions of a desktop TV 450x450x300 mm. Weight 16 kg. According to this design and scheme, but with a 53 cm diagonal kinescope, the plant produced an experimental Almaz-104 TV set, which was also produced in two design options. In the floor version, a stand is attached to the case. The tabletop design also has a stand, but it is much lower than the floor stand. Under the case, on a special board with some inclination, there are two 1GD-9 elliptical loudspeakers. The floorstanding model adds another loudspeaker. The TV uses a 53LK6B kinescope. Resolution in the center of the screen horizontally 500 lines, vertical 550 lines. The band of reproducible audio frequencies for the floor model is 60 ... 10000 Hz, the tabletop is 80 ... 8000 Hz. Sound pressure in the frequency range of 8 bar. The TV is powered from an alternating current network: 127, 220 or 237 V. Power consumption when receiving TV is 185 W; FM stations 60 W. The size of the image on the screen is 370x475 mm. Dimensions of TVs: in the floor design 1120x565x95 mm, in the tabletop 580x565x395 mm. Weight in floor decoration 40 kg; in the tabletop 36 kg. Both models use a volume control with bass compensation. Both models in both design variants have been upgraded in terms of size and weight reduction.
