Not sure what I expected to see inside - but it was not this!

Fran, you are so cool! ❤️
That's really weird.
I love the fascinating artifacts you find for us to enjoy.
Project Farm would have tested it against other Analog Devices and finally cut it in half to see how it was made.
I have a bunch of those at work that where used over the years at a research lab. The bricks have pins that mate into the sockets you can see on the inside. Usually they would mount to a phenolic board that could be mounted in a chassis with standoffs and the 2 screw holes you saw are to hold it on the board or thos box so it wont wiggle out. You can pop that brick right off the base with a little leverage on each side. Theres no adjustment to it, if it fails you remove it and pop in another. They even made single 5V ones for digital circuits.
The base just lets you use the same supply as maybe powering breadboard circuits or even testing the supplies.
Didn't even try to see if it's working?
when replacing cord Mount the Fuse to back wall on outside : )
It's a demo model for the AC/DC converter on top. It wasn't meant to be a commercial power supply.
Big Clive would usually draw out a circuit diagram for us 👍

It is just a breakout box for a power supply intended to be installed inside equipment.
I have some very similar Analog Device modules hidden away somewhere,, they usually are plug in and have gold pins too.
I bought a lab type power supply from the famous auction site that was like that, but on a greater scale. This thing was huge. It was something like a 30 or 40 ampere supply, with meters, a current limit pot, and a voltage adjust pot. However, it was in two sections, with the "real power supply" completely sealed in a welded can. It had some problem, but I couldn't get to it. I managed to cut one "observation hole," but the metal was thick, and I decided it wasn't worth it, so I scrapped it.
I used those repeatedly 1987 to 1999 at Ames Research Center. The 902 was in the General Services Catalog but not the 950. The 902 did not have the Analog Devices logo on it but it was the same thing. Used it many times for my creations supporting the Vertical Motion Simulator at Ames.

I wanted the full teardown of this power supply.
I need to see the transformer and the regulator circuit. I saw 2 brass potentiometer shafts.
Similar pass-throughs to the ones seen here are often insulated with ceramic or teflon and used to pass RF or power-supply voltage through a metal shield into a TV tuner or enclosed RF/IF circuit.
