Description

Marconiphone television reciever with its back panel removed, revealing its insides. The long cathode ray tube can be seen, filling the whole cabinet. The Model 702 was made by Marconi in about 1936, when it sold for 60 guineas. The image on the horizontal 12 inch screen was reflected onto, and viewed via, the mirror on the lid of the case. Because the cathode ray tube was so long it was mounted vertically in the cabinet. Mounting the tube this way meant that if the tube shattered, the glass flew up in the air rather than directly at the viewer.
