Network lamp radio receiver "ARZ-51".

Tube radios.DomesticSince 1951, the network tube radio receiver "ARZ-51" has been producing the Aleksandrovsky radio plant. The ARZ-51 radio receiver replaced the ARZ-49 model. The main differences between the new model and the previous one are noted in the replacement of the output stage lamp with 6P6S and in the simplification of some circuit elements. The power supply circuit has been changed to a full-wave one with a 6Ts5S kenotron. In appearance, dimensions and weight, the receiver hardly differed from the previous one. Operating frequency ranges: DV 150 ... 415 kHz, SV 520 ... 1600 kHz. Intermediate frequency 110 kHz. The sensitivity of the model is about 300 µV. Sensitivity from the pickup jacks 0.25 V. Selectivity on the adjacent channel at 10 kHz detuning is not less than 20 dB. Image channel selectivity 15 dB. The range of reproducible sound frequencies is not more than 200 ... 3000 Hz. The output power on the new 1GD-1 loudspeaker at 10% THD is about 0.5 W. Power consumption from the network is 40 watts.
