The portable transistor tape recorder Reporter was developed in 1956 at the GI Petrovsky plant in Gorky. The Reporter compact recorder is designed for recording interviews; it is a compact and lightweight device, completely made on semiconductor devices. No other information was found on this device. The tape recorder remained a prototype released in small quantities. The reason why the tape recorder was not put into production was the imperfection of the semiconductor (transistors) of those years, their high noises and the instability of the parameters when the supply voltage and ambient temperature changes. Since 1958 a similar tape recorder has been launched into mass production under the name Reporter-2, but made on mini-radio tubes instead of transistors.
