Description
The București 500 S 593 A is a mains-powered tube radio receiver made in Bucharest by Radio Popular, the factory that became Electronica in 1960 [1]. It is one of the first receivers of Romanian design, built partly with imported and partly with locally made components [1].
Put into production in 1959, it was dedicated to the 500th anniversary of the first documentary mention of Bucharest [1]. Its polystyrene ventilation grilles were among the first parts made at the factory on an injection-moulding press [1].
Because its production continued from 1959 into 1960, when Radio Popular became Electronica, it appeared on the market with brochures carrying either factory’s logo [1].
In the source table, sensitivity is given for 50 mW output, selectivity at 1 MHz for ±10 kHz detuning, the audio frequency response at −6 dB relative to 400 Hz, and output power at 10% distortion [1].
