The network tube recorder "Minia" since 1962 was produced by the Kaunas Radio Factory. The Minia is an upgraded version of the Vaiva serial radio. Models were produced at the same time, but the Minia was often modernized, and the Waiva base radio tape recorder, with minor improvements in the design and layout, was produced until 1967. The "Minia" radio tape recorder consists of an eight-lamp, 5-band, 1st class receiver operating in the DV, SV, KB and VHF range. The range is selected by a nine-button switch, the setting is controlled by an optical indicator.
