Description
The București S 543 U is an AC/DC mains tube radio receiver made in Bucharest by Radio Popular, the factory that became Electronica in 1960 [1]. It was assembled from kits imported from Hungary [1].
The table gives it together with the Carpați S 545 U, which covers medium and short waves [1]. A version for AC mains only was the București AS 543 A [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].
