Children's transistor electrophone '' Electronics ''.
Electric record players and electrophones on semiconductorsDomesticThe children's transistorized microphone "Electronics" has been produced by the Pskov Radio Components Plant since the 1st quarter of 1975. Children's electrophone - toy "Electronics" - designed for playing records with a diameter of up to 25 cm, at a speed of 33 rpm. The speed is adjustable from 30 to 35 rpm (if desired, by modifying the EF, speeds of 45 and 78 rpm can be realized). It is recommended to play gramophone records with speech phonograms due to detonation when playing musical phonograms. The model is powered by two KBSL-05 batteries or, depending on the version of the microphone, from 6 elements 343 with a total voltage of 9 V. In some versions, there was a connector (such as a crown) for external power supply with a voltage of 6 to 10 V (many mistakenly connected a battery there "Krona". Electrophone has a nominal output power of 100 mW at 7% THD, maximum 150 mW at 10% THD. Operating frequency range 200 ... 4000 Hz. Until 1983, the circuit was assembled on germanium transistors, then silicon and a microcircuit. depending on the option, 18 or 25 rubles.
