To what are those two little "domino" looking things connected? (hiding behind the big resistor that's dead center.). Those are mica capacitors, and it looks like they have one lead on the left-hand connector to which an arrow points.

Also, if that orange-brown square with three leads coming out of it is connected to anything relevant, beware that those are usually a package containing a resistor and capacitor network. It doesn't look like it's attached, but just something to keep in mind. Some schematics show the separate components, some show a "magic box", and others will show the internal components outlined with a dashed-line box.

It's also possible that that capacitor is hiding somewhere in the yoke, especially if there's a nearby accessible ground point to which they could run it... It could well be bridging BOTH deflection coils to the ground connection on their other side.

Since most capacitors short on failure (unless they're special line safety caps), the AC test I mentioned will show if it's present regardless of condition... and at least knowing that eliminates some of the guesswork.
