VTD was the [[JVC SVHS]] and VTE the VHS - a sort of cascade of likely picture quality from A to E. A shortage of inputs on the [[Station Video Mux]] at the time lead to the creation of the aluminium switch box that selected between video from VTC and VTE. Nothing more than a toggle switch in a box (termination resistors weren't added until 1998), it is still refered to today as the "VTC/E switch" despite the lack of a VTC or VTE in the station. | ||

Finally in | Finally in 2000 some new heads were purchased, the VHS machine had slowly been losing tracking and £20 was spent on a new drum. Likewise the only remaining Umatic machine had taken a punishing, so £160 was spent on a new drum (fitted on 19th February 2000). The infrequent replacement of the heads meant it wasn't worth buying head alignment tools, and both machines were simply lined up by eye by spinning the drum by hand and looking for excentricity under a bright light. | ||
