The set "Electronics-25" was produced since 1984. The set is designed for high school students, but the simplicity of the structures that can be assembled from the parts included in this set allows us to recommend it to everyone who takes their first steps into the fascinating world of radio electronics, regardless of age. The '' Electronics '' set includes a universal printed circuit board made from foil-coated getinaks, which has 33 numbered pads. On this board, you can assemble 25 different devices, the electrical circuits of which are given in the instructions. Here are the simplest probes and generators, converters and amplifiers, photorelays, and even direct amplification receivers, up to 1-V-2. All necessary parts for this are in the kit. It is very convenient especially for novice radio amateurs that the diagrams give the numbers of the contact pads, to which the details of the device and wire jumpers should be soldered, which greatly simplifies installation and avoids errors. Price set 6 rubles.
