OK got that. Back to my horizontal circuit, specifically the width control and how it influences the horizontal deflection. The yoke is a big electromagnet that bends the electron beam scan using the horizontal windings to deflect the electrons side to side. The vertical yoke when electrified and magnetized determines where the scan starts positionally at the top of the phosphor screen and where it finishes on the bottom. Does the width control, as a variable resistor, potentiate the voltage to the horizontal yoke windings and is deflection left to right dependent on the strength of the voltage induced magnetic strength? It doesn't look to me like it's directly connected (I'll post a better picture tonight) to anything going to the yoke. I understand the role of the permanent magnets, ion traps and electromagnetic focus coils in other TVs providing additional nudges to the beam.
