CTC-40, RCA's first solid state. Bear of a chassis. SCR deflection, single ended vertical output. These are the two areas where i have found semiconductor specs. to be critical.You can change the whole board with the color subsection on it if you are glutton for solder and punishment. I have one that was mint except for a bad flyback until the flood of '99 ruined my stored collection. I still have the rusted chassis and a ctc-41 Chassis that is the same except for flyback\Quadrupler in Hv.sect. You really need a good schematic for it. You need to look for cold solder joints, especially on the wire wrap pins. Could just try changing the xtal, i think the one from a tuber like a -38 or -39 will work
