Description
The Orizont S 620 A is a mains-powered tube radio receiver designed and made by Electronica in Bucharest in the first half of the 1960s [1]. It is an AM-FM set with two short-wave bands and a VHF band [1]. The text gives it 3 W output, the annex 2.5 W [1].
The book counts the Orizont, with the Modern and the Darclee, among the receivers of its own design with up to five wavebands, four loudspeakers and superior performance that Electronica was making by 1965 [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].
