The 180 line cathodic prototype
Built by Roger DUPOUY. Sold in July 2011

Built according to archives, this set is similar to the very first cathodics television receivers, that replaced mechanical television devices in 1936. Nowadays, there are not much 180 lines cathodic television sets in working conditions. Very few people in France have ever saw TV images in this definition.
