This one showed up here at the house today courtesy of an older man who I fixed a console stereo for a while back. It's an '84 19" knob style varactor tuned 19" color set. He claimed that it worked and the only reason he was getting rid of it is because his son bought him a new TV. I have not pulled the back; but, I suspect that it uses the CTC120 chassis, which was a good chassis. When fired up, the grey scale is a little off and there is a lot of interference in the picture. I tried a different matching transformer, without luck. I'll check into it further when I open it. Also, the finish is worn from around the volume control and one of the little hinges on the control door is broken off. I found the broken piece; so, maybe I can glue it back together.
