The &quot;Electronics-25&quot; set has been produced since 1984. The set is intended for high school students, however, the simplicity of the designs that can be assembled from the parts included in this set makes it possible to recommend it to everyone who takes their first steps into the fascinating world of radio electronics, regardless of age. The Electronics Kit includes a universal foil-clad PCB with 33 numbered contact pads. On this board, you can assemble 25 different devices, the electrical diagrams of which are given in the instructions. Here are the simplest probes and generators, converters and amplifiers, photo relays and even direct amplification receivers, up to 1-V-2. All the parts required for this are included in the kit. It is very convenient, especially for novice radio amateurs, that the diagrams show the numbers of the contact pads to which the parts of the device and wire jumpers should be soldered, which greatly simplifies installation and avoids errors. The price of the set is 6 rubles.
