RCA CTC-16XL Suggestions/Tips

Curious that the peaking switch would affect brightness. I wonder if they did something weird, like reduce the video gain (contrast) at the extreme peaking setting so there was more headroom for high frequencies? If I have the time I will have to trace through the schematic to see what's going on.

It's literally what Electronic M said, Video peaking switch is a “a video treble control” hung off the contrast pot, it creates the illusion of adjusting brightness by changing the contrast parameters by choosing one of 3 different capacitors , depending on where the switch is set.
