Description:

Kongres is the successor of the Klasik model manufactured one season before. The only difference is the design of the cabinet. It was manufactured in multiple factories. Not all of them belonged to the Tesla company and that's why the name of the manufacturer is not mentioned in the type name. It is a well-equipped radio - an input band pass filter, switchable band width, "loudness" volume control and an audio feedback circuit with tone registers. The emphasis was also put on usage of good-quality components and ease of repair. The design was based on the Telegrafia Liberator radio, made in 1945/46 in Telegrafia Pardubice.
