Lovely 'scopes. That's one of the later models, in '80s brown/beige. Funny how the earlier blue/grey ones seem less dated today...
What's nice about working on these is how the whole front panel assembly comes out in one bit lump. You start by removing the CRT knobs, as those potentiometers stay behind, but everything else comes out together. Various connectors unplug from the main PCB en route. Having done that, access to all switches, etc, is really easy.
One cosmetic problem we've had is the plastic CRT bezel going brittle with age, so it falls off if you move it around. Otherwise, these have proved to be extremely reliable and easy to use. I like them a lot
