The horizontal and color burst adjustments were done exactly as specified
and the test results were perfect. There is a test specified for this exact thing
in the RCA service man, i.e. Fig. 34 and note in left column of p. 23. Its not
supposed to change as you change the horizontal hold. And it doesn't ... if you use
standard VERTICALLY positioned color bars, i.e. a bar running from top to bottom of the screen.
That's because the standard ones don't have a 100% color intensity along
a lot of the left edge of the picture. True, the real SMPTE ones do have
a bit of blue there, but its so few lines that
it doesn't really show up well looking on your scope for fig. 34. I can barely
see it, expecting it.

I don't have an image, its not needed. Look at a pure 100% intensity
100% saturated 100 screen coverage red field from any test disc. it should be red!
And the top is. But after 1/2 to one inch from the top it turns magenta.
The distance depend on the position of the horizontal hold.
