Since 1959 the reel tape recorder "Kometa" has produced the Novosibirsk Plant of Precision Engineering. The tape recorder "Comet" is designed to record and play music, speech and various noise effects. It allows recording from a microphone, receiver, sound pickup, radio line and recording of soundtracks from another tape recorder. The model used a two-track record. The sound carrier is a ferromagnetic tape of type CH and 1, 2. The tape recorder allows you to record or play back phonograms at a speed of 4.76, 9.53, 19.05 cm / sec. When using cassettes No. 15 with a capacity of 250 m tape, the duration of the recording sound on each of the 2 tracks will be 92 in the first case, 44 in the second and 23 minutes in the third. At lower speeds, it is advisable to record conversational speech and two large pieces of music. The total deviation of the LPM speed from the nominal speed of 19.05 cm / s is 3%. The total detonation coefficient is ~ 0.5%, the frequency of the erase current generator and magnetic biasing is 45 kHz. Sensitivity from a microphone of 3 mV, pickup 200 mV, radio network 10. The range of sound frequencies reproduced at a higher speed is 50 ... 10000, at an average of 100 ... 6000 and at a lower 100 ... 3500 Hz. Nonlinear distortion of the through channel at a frequency of 400 Hz, with a maximum recording level and a nominal output power of 5%. Self-noise level (dynamic range) ~ 35 dB. Rated output power at the maximum recording level on the tape 1.5 watts. The tape recorder is powered by a 127/220 volt mains. Power consumption from the network in recording mode 40, playback 52, rewind 65 watts. Dimensions of the model 410Ñ…410Ñ…210 mm, weight 15 kg. In the tape recorder there are 3 control knobs: a signal level regulator during recording and playback, a tone control, a speed switch, a safety button mechanically blocking the recording from an erroneous erasure, an overlay button allows you to record a new one on the existing recording, while playing, they will be heard at the same time: Keys record, play and stop.The tape recorder is assembled on 3 radio tubes 6N1P, 6N2P and 6P14P. The recording indicator is a 6E5C lamp. The tape recorder used 3 loudspeakers 1GD-9.
