Reel-to-reel tape recorder `` Comet ''.

Tape recorders and radio tape recorders.Since 1959, the Kometa reel-to-reel tape recorder has been produced by the Novosibirsk Precision Engineering Plant. The "Comet" tape recorder is designed for recording and reproducing music, speech and various noise effects. It allows you to record from a microphone, receiver, pickup, radio link and re-record phonograms from another tape recorder. The model uses two-track recording. The sound carrier is a ferromagnetic tape of type CH and 1, 2. The tape recorder allows you to record or reproduce phonograms at a speed of 4.76, 9.53, 19.05 cm / sec. When using cassettes No. 15 with a capacity of 250 m of tape, the duration of the recording on each of 2 tracks will be 92 in the first case, 44 in the second and 23 minutes in the third. At a lower speed, it is advisable to record spoken speech and on two large pieces of music. The general deviation of the CVL speed from the nominal at a speed of 19.05 cm / s is 3%. The total detonation coefficient is ~ 0.5%, the frequency of the erasing and magnetizing current generator is 45 kHz. Sensitivity from microphone 3 mV, pickup 200 mV, radio network 10 V. The range of sound frequencies reproduced at a higher speed is 50 ... 10000, at an average speed of 100 ... 6000 and at a lower speed of 100 ... 3500 Hz. Harmonic distortion of the through channel at a frequency of 400 Hz, with a maximum recording level and a nominal output power of 5%. Intrinsic noise level (dynamic range) ~ 35 dB. Rated output power at a maximum tape recording level of 1.5 watts. The tape recorder is powered from a 127/220 V network. Power consumption from the network in the recording mode 40, playback 52, rewind 65 W. Dimensions of the model 410х410х210 mm, weight 15 kg. There are 3 control knobs in the tape recorder: a signal level control during recording and playback, a tone control, a speed switch, a safety button that mechanically blocks recording from erroneous erasure, an overlay button allows you to record a new one on an existing recording, during playback they will be listened to simultaneously, a key switch of the type of work: record, play and stop keys. The tape recorder is assembled on 3 radio tubes 6N1P, 6N2P and 6P14P. The 6E5C lamp serves as a recording indicator. The tape recorder uses 3 loudspeakers 1GD-9.
