Children's radio construction set `` Start ''.
Radio and electrical constructors, sets.Multifunctional devicesThe children's radio construction set "Start" has been produced since 1970. It is a set of radio components (resistors, capacitors, diodes, transistors, HF transformer, variable capacitor, lamp holder, contact and headphones) that allows you to quickly and safely, without soldering, mount various simple radio devices on transistors. The kit includes a plexiglass circuit board, a screwdriver, a socket wrench, tweezers, nuts with screws and mounting bars, with the help of which the elements are assembled. 12 schematic and wiring diagrams are attached to the instructions for use. With the help of schemes, young radio amateurs will be able to assemble a detector receiver, receivers on one, two, three and four transistors, two and three transistor bass amplifiers, a simple sound generator, a sound generator for learning Morse code, a light pulse sensor, an amplifier for an electrodynamic microphone, a device for transistor tests and a device for connecting the assembled receivers to household radio receivers for listening to radio stations through an external loudspeaker. Any batteries and accumulators with a voltage of 4.5 to 9 V can be used as power sources.
