The combined installation "Temp-9" (teleradiol) was experimentally released in 1960 by the Moscow Radio Plant. The combined installation "Temp-9" consists of a television, a high-end radio receiver "Lux" and a tape recorder "Melody", which is adapted to play stereo sound recordings. In the upper part of the case on the right there is a cover, under which a stereo tape recorder is located. On the left side of the case is a TV set, on the right side is a receiver. In front of the receiver and the TV screen there is a vertical moving protective plate that automatically turns off the TV in the left position and turns off the receiver in the right position. The entire lower part of the case is occupied by an acoustic unit, two broadband low-frequency amplifiers and rectifiers. Connecting the amplifier input to a TV, receiver or tape recorder, as well as switching on the rectifiers, is performed automatically when any of the teleradiol units is turned on using the appropriate relays. There is a chain of interlocks, which excludes the possibility of simultaneous operation of the TV and the receiver, as well as providing for switching off the tape recorder while the top cover is lowered. On the left and right sides of the combined installation are two remote case with loudspeakers. When playing stereo sound recording, the left and right channels are fed separately to these speakers, creating the effect of stereo sound. During the reception of the sound of a TV show or the reception of broadcasting stations, the common speaker of a teleradiol creates the effect of surround sound. All the main control knobs of the receiver, TV and low-frequency amplifier are displayed on the front side, and the tape control knobs are located on top. On the back of the case, the adjustment knobs are pulled out, which are rarely used. Television "Temp-4" works on a superheterodynamic scheme, has a high sensitivity. It uses a 53LK6B kinescope with an electron beam deflection angle of 110 °, with an aluminized screen.Can also be used a 53LK2B kinescope with a beam deflection angle of 70 °. The TV uses the AGC delay and ARA, there is a knob for adjusting the clarity of the image. In order to ensure stable synchronization with weak signals, an inertial self-tuning of the frequency of the rows is introduced into the circuit. For fine adjustment of the TV during its operation is a special indicator settings. Structurally, the TV is mounted on a single chassis. The switch of television channels and the kinescope are mounted on the case walls separately from the chassis. The TV-iore uses 18 electron tubes and 15 germanium diodes. The main technical data of the TV: Sensitivity on all channels 200 mV; horizontal clarity in the center of the screen 500 lines; Vertical definition in the center of the screen 550 lines. In the "Temp-9" installation, the low-frequency part of the receiver is not used due to the fact that there is an advanced low-frequency system with a powerful amplifier in teleradiole. The main data of the "Melody" tape recorder is no different from the data of the basic model. It remains only to indicate some changes in the scheme and design of this tape recorder in this case. A tape head is installed in the tape recorder to play stereo recording simultaneously from two tracks of ferromagnetic lechta. To amplify the signals on the second channel, an additional three-stage amplifier with 2 6N2P lamps was used with an autonomous power supply of the channel of the first 2 stages from a special rectifier. Gain adjustment on the 2nd channel is performed simultaneously by one common knob. When playing a stereo recording, the keys of the first and second tracks are simultaneously pressed, while two through channels (left and right) work. It should be noted that the tape with stereo recording is used only in one direction and to repeat the sound of the same program, the tape must be rewound, therefore the time of the sound of the stereo recording is half the time of the sound of the mono recording with the two-track system. Own amplifier LF tape '' Melody '' excluded. The bass booster has a push-pull output and is assembled along an ultra-linear scheme giving the least non-linear distortion.Outputs for LF and HF are separated and have independent transformers loaded on 10GD-18 and VGD-1 loudspeakers components of the remote unit for each amplifier and on 6GD-10 (2) and VG-D-1 (2) loudspeakers installed in the housing. The tone control is carried out by smooth controls and fixed, corresponding to the cases of the most characteristic sound. Buttons located vertically between the TV and the receiver "orchestra", "jazz", "bass", "solo", "speech" give the opportunity to choose a favorable sound. It should be noted that when the fixed tone is turned on, the smooth tone control remains on and can be used to adjust the tone. The tone control block simultaneously produces corresponding changes in the frequency characteristics of both low frequency amplifiers. Main technical data of teleradiols: Operating frequency band 50 ... 12 000 Hz. The sound pressure developed by the unit is 25 bar. Nonlinear distortion factor: at MF - 7%, HF - 5. The installation is powered from an AC network with a voltage of 110, 127 or 220 V. Power consumption: when the TV is 230 watts; TV and tape recorder 300 watt; receiver and tape recorder 230 W; 150 watt receiver; 180 w tape recorder.
