There wasn't any protective film on the resilvered mirror.
I didn't measure the angle of the plane mirror, so that's worth checking. There is very little range of movement for that mirror, once you have adjusted it so that the CRT is centered and clears the hole. There's a bit of elbow room, however. There are no adjusters for the spherical mirror, which is bolted perpendicularly inside the front wall of the box.
The manuals say nothing about installing or adjusting these mirrors, which was outside the scope of ordinary service, I guess. They must have used special jigs in the factory for this task. Due to X-rays, you can't loosen the mirrors and fiddle with them to watch the effect while the TV is playing, so the process might be tedious:
-- Make a little adjustment.
-- Close up box.
-- Turn on TV and view the screen.
-- Turn off TV and open the box.
-- Repeat as needed.
The manual does describe a bunch of adjusters for the optical system, including one on the corrector lens, but I don't want to mess with those until I confirm that the internal mirrors are installed as well as I can manage.
