Thanks TVTim, I'm enjoying this one.

In sets where the convergence is adjusted partly by tilting the yoke (which also affects centering), and there is no width adjustment, the set would be designed with extra width, so moving the yoke would never produce black edges. Also, solid state sets were often designed with wide retrace pulses to reduce the peak voltage on the horizontal output, another thing cutting off the sides, compensated by the extra-wide horizontal sweep. (Easier for transistor horizontal output stages to produce extra current rather than extra voltage)

That makes sense even though I don't quite understand the pulses, maybe because I don't have a scope and have never seen one in use. Guessing they did that to keep the horizontal output running cooler?

VR201 is the 120 V adjust & near TP30
Width adj shows on L213 BUT it dont show a slug. It does show a dotted line
so its probably a factory jumper. I would not mess with it.

B+ was a tiny bit high at 123 VDC. I let it run for 10 minutes then set it to 120 on the dot. Thanks for that info zeno. I'm going to embrace the extra width. I picked up an HDMI to component adapter to feed my Fire TV stick into the RF modulator. The extra width makes 16:9 content look better.
