Radio amateur set '' Electronics Integral-1 ''.

Radio and electrical constructors, sets.Audio AmplifiersSince the beginning of 1988, the set of the radio amateur "Electronics Integral-1" has been produced by the Tomsk Research Institute of Semiconductor Devices. The set of radio amateurs "Electronics Integral-1" is intended for radio amateurs with basic knowledge of radio engineering and contains assemblies and parts from which a powerful final amplifier of audio frequencies can be assembled according to the given diagrams. Main technical data: Rated output power 50W. The nominal band of amplified sound frequencies is 20 ... 20,000 Hz. Amplifier sensitivity 0.5 V. Harmonic coefficient 0.5%. Input impedance 10 kOhm. A complete design requires an enclosure, a suitable heat sink, and a powerful power supply.
