Subscriber loudspeaker (Toy Designer) "Loudspeaker" since 1986 produced Nalchinsk plant of semiconductor devices. The designer is designed to develop work and amateur radio skills in children aged 12-15 years and helps to develop technical creativity and broadened horizons. From myself I would add that the amateur schoolchildren"™s amateur skills didn"™t improve a lot, except that he advanced his knowledge a little further than a light bulb with a battery to a pocket lamp. But still, one should pay tribute to the plant, how could it meet the selling price of a loudspeaker of 3 rubles 85 kopecks, when retail items cost 10 rubles? I will also add that such designers were sold in the trade network for some reason and assembled at a price of 7 rubles (there was a stamp) but with the guidance of the designer of the toy. The designer was produced in several variants of constructive and external design.
