Re: Jim Hergenrather's note about a 7 second delay. There was only 1 RCA VTR in Grand Central when I left in 1963 and went to build Broadcast Center with the great Team that put it together. Since CBS had a vested interest in Ampex, RCA VTR's were not used in Grand Central. I know that a delay was accomplished between two Ampex machines due to their placement with a wastebasket to determine the time needed... In the Broadcast Center, Ernie Lowe, Paul Buda and I installed one RCA playback-only machine in Video Tape in 1965...all the rest were Ampex. That picture must have been mislabled.
