Yep!
The earlier TS 912 had an explicit color killer stage. It worked by sensing the oscillator grid self-bias, similar to the early cheapened RCA's. Every time I see this, it makes me wonder if the oscialltor was actually free running, or a ringing circuit that died down when the burst went away.
The later chassis (the picture I posted) has no stage called color killer. I haven't figured out if the function is included somewhere else, like the burst gate.
Part of the problem of understanding old schematics is the number of special, multiple-winding coupling transformers used. Later sets with solid state and especially ICs made it possible to get rid of transformers and reduce costs.
