Tube radios.DomesticThe network desktop radio "Record-47" (second version) has been produced since 1949 by the Aleksandrovsky and Berdsky radio factories. In 1949, the Record-47 radio was modernized. Changes were made to its electrical circuit, the ratings of some elements were changed and the appearance of the radio was changed. In addition to the wooden case, versions of the radio receiver in a plastic and iron case were developed, which, however, did not receive widespread distribution. The name of the radio receiver remains the same, "Record-47". Ranges of received waves: DV - 150 ... 415 KHz, SV 520 ... 1500 KHz, KV 4.28 ... 12.1 MHz. Intermediate frequency 110 KHz.
