Ok, I checked the +63/-63V on the board at pins 1 and 7 of both the
connectors to the deflection transistors, and they both read ok. The
size/centering adjustments do not appear to move the lines where the
vertical and horizontal deflection fails. So I don't have full +Y and -X
deflection. Any ideas? What's next to try?
