Description

The Privighetoarea S 623 A is a mains-powered tube radio receiver designed and made by Electronica in Bucharest in the first half of the 1960s [1]. It belongs to the family of AM receivers with three wavebands, 1.5 W output and 3 + 2 tubes [1]. It has the same circuit and characteristics as the Select S 625 A and the Select 2 S 633 A; the three differ in the shape and size of the cabinet and in the loudspeakers [1]. It has its own record player with a piezoelectric crystal cartridge and three speeds [1].

In the source table, sensitivity is given on medium waves for 0.5 W output, selectivity for a signal ±9 kHz (AM) or ±300 kHz (FM) away, the audio frequency response at 1 MHz within 6 dB, and output power at no more than 10% distortion; the quality classes are only indicative, based on IEC recommendations and the Soviet GOST 5651/1951, as Romania had no such standard at the time [1].
