RCA CTC-5 Westcott help

Another hint about the dynamic convergence on this chassis: it is AC coupled. This means that the center (DC) convergence moves when the dynamic is adjusted. One way to approach this (with a cross hatch pattern) is to first set the center DC, then adjust the dynamic controls to get parallel lines, then re-adjust the DC, which should superpose the parallel lines, at least approximately. Then you can do some fine dynamic touch up if you want, but don't get obsessive, because it will never be perfect everywhere. You can spend hours chasing slight misconvergence from one corner of the screen to another.
