Looks like a power supply built specifically for some particular application.
Maybe for somebody to run variable voltage tests on devices he was specifically testing.
You'll probably get a response from somebody here later that might be of more help to you.

Definitely contains some sort of DC power supply. From the front panel labels, it could be a gauss meter, used to measure magnetic field strength with a Hall-effect probe perhaps. Or maybe it is used to excite an external coil with who-knows-what method for detecting the resulting magnetic flux. Why it would need a variable mica trimmer capacitor is a mystery. Very poor construction techniques, but you may be able to salvage some good parts from it for other projects. I doubt this treasure has anything to do with amateur radio, but then I haven't seen everything Hams dream up yet. I wonder what the 5 4-wire ribbon cable connected to?
The rotary switch, the toggle switches, perhaps the potentiometers, the mains power cord, the 5-way binding posts all look salvageable. As do the two 150 ohm 5 watt power resistors, and maybe the power transistors and (unseen) rectifier diode(s) too. And the variable mica trimmer of course. The two electrolytic capacitors are problematical... may be too old and the electrolyte dried out by now. You should fire it up and check for AC ripple. The socket-mounted integrated circuits could be used for an artwork collage. My wife collects used electronics parts, like obsolete PC memory expansion sticks, for this purpose. Maybe you could use the box for another project. I like to hang onto old power transformers too... never can tell when a project will pop up that happens to require whatever secondary voltage the transformer produces.
Nice find, @Gramps!
Edit: Took a closer look at the ribbon cable: four wires, brown, red, orange, and yellow.

So, Gramps, what are you gonna do with this blast from the past? Salvage the parts? Mount it in a shadow box on the living room wall? Throw it away?
Would be glad to donate them to anyone who wants to pay the postage to receive them.
Don't have much time for tinkering with electronics anymore sad to say
A little history on these items. I'm on the staff at the Fort Myers Rescue Mission the homeless shelter in Fort Myers.
These two items came with a donation and the owner died so we have no way of knowing what the equipment was used for.

I have a friend who had his telescope hooked up to a monitor so he could do his viewing from inside the house and not have to be out in the cold. Maybe this gizmo could have been part of that feature. But really just a guess from left field. Thought it was worth posting tho.
