* It works. CC, CV work as expected. It hums at 60hz, and gets louder when you load it. 0-20V, 0-10A. * The exterior is in stunningly good shape considering it’s age. Nearly new looking, except for the meter itself (see below). The rubber feet are still intact and not brittle. * The interior is _pristine_. Zero corrosion on the PCB (lighting in the photo makes it appear to be, but it’s all very shiny and golden). The wires are all still pliable, and in good shape. None of the caps appear to be bad/bulging. * The manual is readily available, and includes full schematics.
The Bad:
* The front panel meter is pushed in; this was known when I bought it. I need to 3D print a new bezel/bracket. * The meter range selector knob was flaky; would peg the meter when jiggled. Took it apart, worked it with liberal amounts of contact cleaner, now it’s working great. * When I received it, one of the exterior screws had come off, and it’s _interior_ non-captive nut was rattling around inside.
The Ugly:
* The meter reads about 15% low. Needs a bit of calibration. * It’s rather large. And heavy.
~$100, including shipping

Overall I’m rather pleased.
This is fucking beautiful
The thing i love about old circuits is the fact that they all are hand designed so basically each one of them is an artwork itself.
I miss the days when manufacturers didn’t fuck around. This is right up there with Northrop Grumman.
Someone had to sell a kidney to afford one of these back in the day I’m sure.
Look at that! Another vintage HP. 11 transistors in the whole thing.
In mine they’re even socketed transistors.
