Early Color Television CBS RX-40/41 Color Converter/Adaptor The RX-40 Converter (in front of the TV set), and the RX-41 adaptor (on the left of the set)
This converter was made by CBS in 1950. It was mounted in front of a 10 inch RCA 9-T-246 black and white set. In the black and white mode, the converter slides to the left, allowing the 10 inch picture to be viewed. In the color mode, the unit is in front of the picture tube. A switch on the adaptor reduces the size of the picture to about 7 inches diagonally. When you view the picture through the magnifying lens, it looks to be about 10 inches. Here is a Popular Science article featuring the converter. The unit was missing the slide assembly. We have made a replica, which looks somewhat like the original. It was also missing its color wheel, but we have made a replica. The converter was attached to a RCA 9-T-246 using the RX-41 adaptor. It contains a separate horizontal output section, with a voltage doubler to make the picture brighter in the color mode. Our adaptor was missing its flyback transformer and wiring harness. We have restored the Converter and Adaptor. Here are some photos off the screen:
