Radiola network lamp '' Record-61 ''.
Network tube radiosDomesticThe network tube radio "Record-61" has been produced by the Berdsk Radio Plant since 1961. Radiola is designed for reception in the ranges of DV, MW and HF (76 ... 24.8 m) waves. The three-speed, 33, 45 and 78 rpm electric radio player allows you to play regular and long-playing gramophone records. Intermediate frequency 465 kHz. Adjacent channel selectivity 30 dB. Sensitivity on all ranges 200 μV. The output power on two 1GD-5 loudspeakers is 0.5 W. The range of reproducible frequencies when receiving 100 ... 4000 Hz, when playing records 100 ... 6000 Hz. The power consumed from the mains when playing records is 55 W, when working at a reception of 40 W. The installation of the radio is made in a hinged way. In the first issues in the converter there was a 6A7 radio tube. In 1962, the radio was modernized with a new, more modern case. The electrical circuit of the radio has remained the same, but the installation, in addition to the contours, was carried out in a printed way. The letter "M" appeared in the documentation and diagrams of the radio (not everywhere). The radiola was also produced in an old case, and in larger quantities. In 1962, an attempt was made to release a radio tape recorder "Record-61" with a key range switch and in a new design, but it did not go further except for the manufacture of experimental radio tape recorders. The radio "Record-61" in 2 types of case design was produced until August 1965.
