Say Good-Bye To Burbank

NBC Burbank is barely older than I & while NBC & Burbank were even more synonymous than Disney & Burbank it will be completely over by next yr. (while ironically ABC Tee Vee has moved to the Dis lot in Burbank). A brief history.

Getting-to-be-obligatory ha ha you young people have no idea how it was in our day bit:
A bank of multiple RCA TK40 color camera setup controls.
Note the identical sets of knobs for red, blue and green adjustments.
From RCA Broadcast News #77, January, 1954
A 1950s color telebision camera weighed over 300 pounds and required very bright lighting. Within each one were three complete black and white pickups, large photosensitive vacuum tubes known as Image Orthicons. In the first color cameras, the image traveled through a dichroic prism that split the light into the three primary colors (red, green and blue) each of which was directed at one of the three black and white Image Orthicon tubes.

To recombine the black and white images into color, engineers developed the art of “Registration.” By adjusting a myriad of controls repeated in triplicate for each primary color (a process that took over an hour) the three signals were made line for line identical, but even after registration the vacuum tube circuits would drift and require frequent adjustment to maintain the delicate registration and color balance of the three separate signals. Nonetheless, when properly tuned these early color cameras rendered excellent color pictures.
(Edited into English because the guy's a fucking engineer.)

Non-Burbank but closer to home bonus, the northeast corner of Sunset & Vine, 50 yrs. ago.
NBC Hollywood, the site of many classic radio shows & early
television productions, under demolition in 1964.
A bank occupies this portion of the site today.
