Cool. The resistor has been left shorted.

Done, and *wow*, what a difference. More to the point, I'm amazed
at how "large" the screen had bloomed to without my noticing as the
original caps aged.

Looking back at the burn-in on the screen, I noticed a "streaked"
appearance, indicating the lettering in the attract mode had slowly
been growing in size over the years when the machine was in the
arcade. 20/20 hindsight, anyone?

Meanwhile, my thanks to John for the tip.

Later,
Doug.
