vintage:
I make those converters, one of which is for use with the Col-R-Tel. It's not strictly a replacement for the existing electronics, but an improvement over the original. With the original you had to cut into the television for horizontal, vertical and video taps, and start with a tv that had high enough video bandwidth to pass the chroma signal. With the converter, the sequential color video is sent to the tv through RF or line level, so no modification to the tv is required. Because of this you can easily move the color wheel from set to set. All that is required from the Col-R-Tel is the wheel assembly and motor control. If you are ambitious, you can design your own color wheel or drum and motor control like Cliff has done.
