1930s television, 80 years old, restored and working

This is a short video of a Murphy A56V television from 1938 playing the 1946 BBC demonstration film called "Television is Here Again". The television was a complete wreck when I obtained it, and it has taken 3 full years to do a complete rebuild/restoration of the set to get it into working operation. I have not yet put online any photos of the set, either before restoration, or after. But I will try to do so in the near future. In the meantime this page (http://www.earlytelevision.org/murphy...) on the Early Television Museum website has a photo of this set pre-restoration (supplied by the previous owner), and a contemporary 1938 picture of the front and back of the set. Murphy made about 1500 of these televisions between 1938 - 1939, but then television transmissions closed down due to the outbreak of World War 2. Less than 8 are known to have survived, and is quite probably the only one restored to working operation. The video and sound signals are being converted from 625 line PAL composite video/LR audio (off DVD) to the 405 linesystem using an Aurora standards converter, which produces the original 45MHz/41.5MHz RF cariers (original wavelength of the Alexandra Palace transmitter) which are fed into the aerial socket of the Murphy A56V.
