In some reference books the Ladoga-1 TV is sometimes referred to as the Ladoga-201, although it is one and the same TV. The second class lamp-semiconductor TV "Ladoga-1" (LPPT-47-II-1) was created on the basis of the TV set "Aurora". The TV set is designed to receive programs on any of the 12 channels. The device uses an explosion-proof picture tube of the 47LK2B type. The size of the visible image is 380x300 mm. Sensitivity 50 μV. Sharpness is 450 lines horizontally, 500 lines vertically. The nominal output power of the sound channel is 1.5 W. The band of reproducible sound frequencies is not more than 100 ... 10000 Hz. The tone is controlled by bass and treble. The TV is powered by a 127 or 220 V power supply, consuming 175 watts of power. The dimensions of the model are 435x610x348 mm. Weight 29 kg. In comparison with the basic TV "Aurora", the new model has increased sensitivity, improved protection of the kinescope from a bright spot after switching off, applied new scanners. In the sound channel, three lamps are replaced by transistors. Added slots for recording audio with a tape recorder and for a dual-language set-top box. The Ladoga-1M TV, produced since the fall of 1969, in addition to adjusting the denominations of parts, does not differ from the Ladoga-1 model. According to the design and layout of the TV "Baltika", the Leningrad plant "Radiopribor" since 1969 has been producing the TV "Atlant" in design similar to the model "Ladoga-1".
