Car radio and electrical equipment.Car radio and electrical equipmentSince 1948, the automobile radio "A-4" has been producing the Murom radio plant. "A-4" is a modernization of the "A-695" receiver (the "A-3" radio receiver was also produced in a small series), which made it possible to use it in the "GAZ-12" car, in which the battery voltage is 12 V. the receiver circuit remained almost unchanged, with the exception of the filament circuit, where a series-parallel connection of the filaments of individual lamps was used. The power supply of the anodes of the lamps is carried out through a vibration transducer, structurally made separately. The characteristics of the receiver are similar to those of the "A-695" model. The receiver was produced until the end of 1952.
