Polonez radio-gramophone

The *Polonez* radio was manufactured in 1956-1958. The device allows reception of radio signals in the short, medium, and long wave bands. It is the first Polish radio receiver with a built-in electric gramophone. It is a six-circuit superheterodyne equipped with four vacuum tubes, one of them acting as a rectifier. The design of the *Polonez* is a developmental version of the *Mazur* radio. The built-in electric gramophone (with the drive applied on the edge of the turntable), allows playback of microgroove and normal groove records. In the *Polonez* receiver, the horizontal box layout already present in the *Mazur* model was maintained, except that the top wall of the housing was lowered by adding a lid on it to create a niche in which the gramophone was placed. Visually, the Polonez is a variant of the *Pionier* radio.
