ITV Channel 11 Test Transmitter.

[Brianc]

BBC Television Centre (God rest its soul) had a 50V battery room initially and there was a huge distribution system throughout the technical areas. Each studio had an incoming 50C did board with butterfly fuses etc. The room was similar the that described by Jeffrey except the battery comprised cells about 24" x 12" x 24" high and the busbars were smaller. Nevertheless, almost as frightening as an early RCA TV transmitter I saw in Iraq. That was in a wire cage and could be heard "bristling" - euch!
