The Motorola chassis with the single-tube color section needed an adjustment because changing the single tube would change the grayscale tracking. Nevertheless, they eliminated the control in the very cheapest sets.

It's interesting that Magnavox and others put the control in as a feature, when they did not need it. I have always thought of it as one more way for the customer to screw up the picture.
