Some sets had a combined Purity Rings/Blue Latteral assembly and thus had only 4 things on the neck.
The convergence yoke typically has more and smaller wires than the deflection yoke that lead to a circuit board with a lot of knobs (known as the dynamic convergence board).

There are these circular ring things on the clover. I guess those are the purity magnets? I will have to take a picture of it and post it here.
