I bet each tube was tested for performance and the IO tubes were hand selected and mated with hand selected yokes.

The low band color standard was not quite agreed upon at that time, hence there were various modes of pre-emphasis being experimented with. It is about 29 minutes long. The program starts in black and white, showing President Eisenhower arriving outside the WRCA studios. Later inside, General Sarnoff pushes a button signifying the inauguration of the WRCA new color studios. As he pushed the button, the color encoder switches from a mono picture to color.
