Interactive exhibition of working Tesla TV sets

In July 2013, at the occasion of 60-year anniversary of the beginning of the first TV broadcasting, the exhibition of several working TV sets was open. These TV sets present interesting milestones in history of the production of this consumer electronic. The TV sets were borrowed from a private collection and for the occasion of the exhibition they were restored and revived again in workshops of Martin Hajek (www.oldradio.cz) and Historical Czechoslovakian Radio-club (www.hrcs.cz). The exhibition will last till cancelled.

In May 2015, we managed to extend the exhibition with two portable TV sets which represent a sample of possible receiving TV signals at the cottages or campsites without a need of a firmly mounted receiving antenna. There is also another addition: a VCR, which began a long and popular era of recording images and sound on magnetic tapes in VHS format.
