Since 1959, the radio receiver and radio network lamp "Melody" have been produced by the Gorky Lenin Radio Factory. At that time, almost any model was adopted to produce in two versions. Someone needed only a receiver, and to someone, mostly young radio. And why overpay if only a receiver is needed. For the production it had a lot of problems and since 1960 all lamp models, with rare exceptions, were produced only as a radiometer. The "melody" of the second-class seven-lamp radio receiver, which differs from the radio line only in the absence of a universal 3-speed EPU - the 2nd class. The models have the following cascades: UHF and FM frequency converter on the 6NZP lamp. UPCH for VHF range and converter for other ranges on 6I1P. Combined UPCH of all ranges on a 6K4P lamp. Combined detector AM / FM signals on 6H2P. The range of received frequencies: DV - 150..415 kHz, SV - 520 ... 1600 kHz, HF-1 3.95.7.7 MHz, HF-2 9 ... 12.1 MHz, VHF-FM 64 , 5 ... 73 MHz. IF on AM path 465 kHz, FM 8.4 MHz. Sensitivity in the ranges of AM 200 µV, VHF-FM 20 µV. ± 10 kHz detuning selectivity in the DV, MW and HF 25 dB bands. In the VHF band with ± 250 kHz offset, 20 dB. The bandwidth of the radio receiver provides reproduction of sound frequencies in the UHF band and when playing records of 80 ... 7000 Hz and 80 ... 4000 Hz when working in the AM bands. Power consumption is 75 W when EPU is working, 50 W when receiving radio. Rectifier selenium. The speaker system consists of two loudspeakers. EPU with asynchronous motor and hitchhiking. The piezoceramic pickup has two corundum needles. The price of the radio is 70 rubles, the radio line is 80 rubles 50 kopecks since 1961.
