Topaz OT 2141 television set

In Poland, production of TV sets began in 1956, at the Warszawskie Zakłady Telewizyjne (WZT). The first receiver was the *Wisła*, made under Soviet licence. One of the many products of WZT of the 1960s is the *Topaz* black-and-white television set. Technically, the device is a modification of the *Agat* receiver of 1964. The *Topaz* was manufactured in versions with a 21” or 23” CRT, both of which were designs with a deflection angle of 110°, allowing the receiver to be put on a shelf or on a chest of drawers. Unified Polish television sets, of which the *Topaz* is an example, set out a new direction for the development of Poland’s television industry, represented by three enterprises operating within the framework of the Unitra union: WZT, Zakłady Diora w Dzierżoniowie, and Gdańskie Zakłady Telewizyjne.
