NBC Burbank was dedicated on March 27, 1955. It was completed in 1962. It is scheduled to be replaced by facilities the NBC Universal is building on the Universal lot. The Olive Ave. property will be sold.
Tuesday, April 28, 1958 is the anniversary of the dedication of Videotape Central at NBC Burbank. The tape facility inside 3000 West Alameda (at Olive Ave.) cost $1.5 million when it was started.
The first recorders were a pair of Ampex VRX-1000’s, two of three units ordered for NBC in 1956 after Ampex unveiled the Mark IV prototype at the NAB convention in April.
The third was shipped to RCA’s labs in New Jersey, taken apart to see how it worked, and used as the basis for a successful color recording system.
NBC began time-zone delay from the Burbank tape facility when Daylight Savings Time began in 1958.

At that time, the facility included one RCA “VTRX” Color Video Tape Recorder, pictured here.
This pre-production model was laid out differently than production models due to Burbank’s plant needs, according to RCA’s A. H. Lind in a 1958 NAB presentation.
In the top photo, the left-most rack had power supplies. Second from left had head wheel servos, motor driver amps and capstan driver amps. The third from left had the capstan servo control chassis, tone wheel amp and 240 cycle refference signal.

There was a lot of dancing going on in order to recover those early entertainment tapes.But that’s another story, to be described on the “Fred Astaire” pages, yet to come.
