Hue Control On GE 15CL100

[Tom9589]

After looking at the schematic on the 15CL100, I noticed that the Hue control is actually mounted on the rear chassis and looks to be a screwdriver adjust. I know that GE uses a different 3.58 MHz oscillator than RCA and the others, but is the GE circuit stable enough to satisfy the consumers or did GE underestimate the need to periodically adjust the hue?
