Yes, there are several mechanical adjustments, as the Rider manual shows in detail.

I temporarily reconnected the broken wire with a clip lead, which brought back the power supply and full deflection. Now I'm back where I was before, with lousy focus. This is the best I can get using the two electronic focus controls:



The focus on the CRT face looks good to my eye, so I'm guessing that one or both of the reinstalled mirrors is cockeyed. I didn't mess with any of the mechanical adjusters before, such as the tilt adjusters on the base of the box. It's possible that some adjuster was seriously screwed up long ago, but the image that I got before resilvering the mirror was much closer to focus (and correct screen geometry) than this. Maybe I'll spot something obvious after I open the optical box back up.
