Top is before alignment. Bottom is after. The hue was 90 degrees out of phase when the chroma bandpass is optimally aligned. De-tuning it slightly allows for the tint control to get the correct hue when the tint capacitor is turned to minimum capacitance.
A better design would be for Magnavox to have chroma tint control after the chroma bandpass, so that alignment of the bandpass doesn’t impact the hue.
