CRT Projection Angle Adjustment
The projection angle of the red and blue CRT's is dependent on the
desired size of the projected image. If the centers of green, blue and
red do not coincide, the CRT projection angle must be adjusted.
NOTE : Never try to correct this misalignment with the shift
correction or the static convergence controls. These controls may
only be applied to correct small errors which cannot be corrected
by the CRT angle adjustment.
Note: The Horizontal Shift and Vertical Shift for Red and Blue
should be set near 50%.
Be sure that the rasters are centered on the CRT faceplate.
