Śląsk radiogramophone

Description

The Śląsk (Eng. Silesia) tabletop receiver with a built-in gramophone was manufactured in 1956-1959. It is the first radio developed in Poland in which a button range switch was used instead of a rotary switch; it is also one of the first radios in Poland to be equipped with a UHF-FM module. Its head operates in a super-reaction arrangement. The Śląsk allows reception of radio signals in ultra-high frequency, short, medium, and long wave bands. It comprises frequency modulation (FM) and amplitude modulation (AM) systems. In terms of electrics, it is an AC-powered superheterodyne using vacuum tubes. The radio has automatic amplification adjustment, which makes the Śląsk less sensitive to waves fading out or being overdriven. The entire device was enclosed in a box housing of polished wood.
