Description
The Modern S 626 A was the top-class tube radio receiver made by Electronica in Bucharest in the first half of the 1960s [1]. It covers long, medium and three short-wave bands plus FM, and has four loudspeakers driven by a push-pull output stage with two EL84 tubes [1]. The text gives up to 8 W maximum output at 10% distortion (and a slightly different tube list, with an ECL85); the annex gives 5 W nominal output [1].
The book counts the Modern, with the Darclee and the Orizont, 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].
