Intriging. Being a fanatic for DC restoration, making it even for B&W portables, I first think that the DC restoration is a rule for color TV (years ago). But then, reading some schematics and restoration reports, I concluded that several models not have it then (since I not read all schematics of all models, of course ;-). Then all tube-based color ones lacked DC restoration? Interesting to know.
Even considering the low light output, the colors will not strongly mistrack with this?
I know the set without DC restoration have a average light output, so this can account for that, along with tracking, I guess... (and so more I bet)

Here in Brazil color comes late, in 1972, but the schematics that I seen, of hybrid sets, have DC restoration (at least for the ones I got schematic), but I bet the track are poor, since not have stabilized PSU, video out tube will drift etc, and color sums "high level" (like most out there, also), using the grids of CRT as input for the color signals. Since I born in 1983, I only seen one of these hybrid sets working. All others are transistor ones with fully DC restoration... so I have almost no experience in watching one with this image properties.
