Radio constructor `` Olymp-1 '' (Power amplifier).
Radio and electrical constructors, sets.Audio AmplifiersThe radio designer "Olimp-1" (Power Amplifier) has been produced by Vinnytsia Central Design Bureau since the 1st quarter of 1980. The Olymp-1 set contains everything you need to assemble a power amplifier: transistors, resistors, capacitors, diodes, a printed circuit board, heat sinks for powerful output transistors, a wiring and shielded wire for input and output circuits. The power amplifier can be used in conjunction with a tape recorder, receiver and other signal sources with an output voltage of 200 ... 250 mV. To power the amplifier, an unstabilized bipolar source is required, with a voltage of 2x20 volts with an average, grounded point. Main technical characteristics: rated output power at a load with a resistance of 4 Ohm, with a harmonic factor of not more than 1% - 10 W, maximum at least 25 W. The range of reproducible frequencies is 20 ... 40,000 Hz, the sensitivity at rated output power is 300 mV. The total current consumption at rated power is about 1.5 A. The input impedance of the amplifier is about 10 kOhm. The retail price of the UM radio designer is 19 rubles.
