Top-class radio tape recorder "Leningrad-003".

Cassette radio tape recorders, portable.DomesticThe top-class radio tape recorder "Leningrad-003" was developed and prototyped in mid-1972. In 1972, the All-Union Scientific Research Institute of Radio Reception and Acoustics (VNIRPA) completed the development and production by the Leningrad plant "Radiopribor" of a small batch of portable tape recorders "Leningrad-003". It is not known exactly how many, according to some sources, about a dozen copies. The model uses the most advanced CVL of those years, from the "Spring-305" tape recorder with a revised key mechanism for vertical pressing. The radio receiver "Leningrad-002" was used as the basis of the model; it was developed here at VNIIRPA back in 1971, but was not serially produced until 1975. The radio tape recorder has a separate recording level indicator, a tape meter located on the top panel of the radio tape recorder. The sockets for inputs and outputs are located on the rear wall. The speed of pulling the magnetic tape is 4.76 cm / sec. The operating frequency range on the LV is 63 ... 10000 Hz, and through the built-in AC - 80 ... 10000 Hz. The rest of the characteristics are similar to the corresponding characteristics of the receiver. Apparently because of the differences in the classes, the tape recorder barely lasted for the second class, really the third, and the receiver was of the highest class, the experts of the All-Union Chamber of Commerce did not approve the "Leningrad-003" radio tape recorder for serial production. Ready-made radio tape recorders were sold to VNIIRPA employees and the further fate of these radio tape recorders is unknown. The radio tape recorder "Leningrad-003" shown in the photo is the only confirmation of the development, which was published in the magazine "Radio" No. 11 for 1973.
