Tape recorders '' Vesna-307 '', '' Vesna-308 '' and '' Veschna-308-1.

Cassette tape recorders, portable.In 1983, the "Vesna-307" cassette recorder was produced in a small series by the Zaporozhye Electric Machine Building Plant "Iskra". A tape recorder of III complexity group "Spring-307" provides recording of phonograms with subsequent playback. It provides the ability to: automatically stop the tape recorder when the magnetic tape ends and the cassette fails; automatic adjustment of the recording level; control of the recording level by two peak indicators on LEDs; the use of magnetic tapes of two types; switching tape types; separate tone control for treble and bass. The noise reduction system provides a decrease in the relative level of noise when playing magnetic tape. The presence of a three-decade tape consumption meter with a reset button allows you to find the necessary records and determine the consumption of the magnetic tape. Power is supplied from seven A-343 elements or from the network using a built-in rectifier. The body of the tape recorder is made of impact-resistant polystyrene. The device comes with two MK-60 cassettes. Specifications: Type of magnetic tape A4205-3; A4212-3B. The speed of the CVL is 4.76 cm / s. The working range of sound frequencies, when using a magnetic tape of the type: A4205-3 - 40 ... 10000 Hz, A4212-ZB - 40 ... 12500 Hz. Knock coefficient ± 0.3%. The harmonic coefficient on the LV is 4%. The relative level of noise or interference in the recording-playback channel with UWB when using a magnetic tape: A4205-3 - 53 dB, A4212-ZB - 55 dB. Output power: maximum 2 W, nominal 1 W. Power consumption from the network is 10 watts. Dimensions MG - 359x185x85 mm. Weight 3.3 kg. Since 1984 the plant has been producing (also in a small series) an improved "Spring-308m" tape recorder, which is practically the same as the "Spring-307" model. Since 1985, on the basis of the previous model, the pilot production of the "Vesna-308-1" tape recorder with a stereophonic path to the LP, with the ability to listen to stereo phonograms on headphones, has begun.
