I read an article about an all-tube 'standards converter' built by the BBC in the late 1950s-early 60s to convert the French 819 line signals to 405 for Great Britain.
I don't mean the earlier ones from 1951 using a camera trained on a CRT either.
This converter, as best as I recall, was built in an entire 6 story building and did the conversion completely electronically, all with tubes! The airconditioning system drew more power than the tube electronics did.
I tried finding the article again [Wireless World?] but no luck. I did find information about a 'line store standards converter placed in operation at the BBC in 1963', but no description of it. If anyone has more info about this converter I'd really like to know.
