This is a studio monitor made in 1950 for use with the CBS field sequential color system. It has a 10 inch picture tube with a color wheel in front of it. This unit is missing its wheel, motor, and lens. It is the only known surviving field sequential studio monitor. Click for more details and pictures.

We have completed restoring the monitor, and have built a color bar generator for the CBS field sequential system. In addition, Darryl Hock has built a NTSC-CBS converter converter to allow broadcast TV to be viewed.

Here is a photo from the screen of the color bar/grey scale pattern.

Photos of the screen using the NTSC-CBS converter made by Darryl Hock (more will be posted about this later). The color actually looks better on the screen than in these pictures.
