Radio receiver and radiola network tube "Melody".
Network tube radiosDomesticSince 1959, the radio receiver and radio tape network "Melodia" have been produced by the Lenin Gorky Radio Plant. At that time, it was customary to produce almost any model in two versions. Someone only needed a receiver, but someone, mainly the youth of the radio. And why overpay if you only need a receiver. For production, this had a lot of problems and since 1960, all tube models, with rare exceptions, were produced only as a radio. "Melody" seven-lamp radio receiver of the second class, which differs from the radio only by the absence of a universal 3-speed EPU - 2nd class. The models have the following stages: UHF and a frequency converter of the FM range on a 6NZP lamp. UHF for the VHF range and a converter for the remaining ranges on 6I1P. Combined UPCH of all ranges on a 6K4P lamp. Combined detector of AM / FM signals on 6X2P. Range of received frequencies: DV - 150..415 kHz, SV - 520 ... 1600 kHz, KV-1 3.95..7.5 MHz, KV-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 AM 200 µV, VHF-FM 20 µV. Selectivity at ± 10 kHz detuning in the LW, MW and HF ranges of 25 dB. In the VHF range with a detuning of ± 250 kHz 20 dB. The bandwidth of the radio receiver ensures the reproduction of sound frequencies in the VHF range and when playing records of 80 ... 7000 Hz and 80 ... 4000 Hz when working in the AM bands. Power consumption 75 W during EPU operation, 50 W during radio reception. Selenium rectifier. 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 is 80 rubles 50 kopecks since 1961.
