Width on RCA CTC-11 ?

[Phil Nelson]

Today's dumb question. The verticals on my RCA CTC-11 now look OK by my low standards, but the width is a little too great. Notice the "ion" icon at lower right in the photo. It's more annoying with other program content, such as a news broadcast or sports. When looking at a crosshatch pattern, it's quite obvious that the width could be brought in.

I see no adjustment for width per se. The set has adjusters for horiz. linearity and centering, but there's nothing wrong with those. I have set the HV at 21.8 KV as shown in the schematic.

Ideas? Is this one of those things that magically changes when you adjust other parameters?

(Ignore the colors, brightness, etc. Neither set is perfect in this snapshot.)
