Paul Marshall reports on an ambitious project – on a small scale
Since the beginning of lock-down, hardly a day has gone past when some aspect of the old main Marconi Chelmsford works hasn’t been re-invented here at our base near Lincoln.

Trevor Brown has been documenting his work in breathing new technology into a vintage Grass Valley video mixing console; you can read the entire series of articles in his free CQ-DATV electronic magazines, starting in issue 68.
This led me to think about the even older history of video mixers generally.

Peter Scott’s Nostalgia Site at www.nostalgiatech.co.uk covers some of his interests but is principally dedicated to the SS Jaguar motor car, the first Marconi/EMI television receivers, and the Emitron Camera.
Paul’s latest “lockdown” report:
Here is a picture of the new Marconi Mk III camera test facility that I’ve put together.

A new approach to technological television history and conservation
By Dr Paul Marshall
How does traditional analogue television work? That’s a question beyond the comfort zone of most media historians who may not be familiar with analogue electronics. Even young engineers know little of thermionics, cathode rays and a myriad of other forgotten technologies. This important facet of television’s history is now only recorded by older engineers and by amateur groups who collect these technologies. In this paper, I will show by using examples how material artefacts can help us understand television’s history more fully.

One of the problems that we have always noted with Southern is the lack of space for distribution amplifiers, for both video (VDAs) and pulses (PDAs). Rack space is in very short supply after accommodating four Marconi MkVII camera control units with power supplies, aperture correctors and coders, plus the space required for monitors and the mixer electronics, so we had only fitted one set of distribution amplifiers.

From the late 1960s through to 1981 (when they lost the broadcasting franchise for the southern region), ITV Southern Television was unique in the world in having a dedicated outside broadcast boat.

Dicky Howett recalls a little piece of ABC Television at Didsbury.
In a residential street on the outskirts of Manchester there used to stand the production base of ABC Television. (You remember ABC Television? Come on now, that was back in the days when ITV was ITV!). Demolition, it seems, is the pre-ordained fate of most pioneer tv establishments. For example, A-R tv’s Wembley got razed and recently, the big double production space known as ‘Studio Five’. Teddington Studios became an upmarket riverside residential enclave; Television Centre – sold for a pittance; the London Studios are not what they used to be; Lime Grove bit the dust and Alexandra Palace… well who knows? However, redundancy is the name of the game and sentiment doesn’t enter the balance sheet.
