Hand tool rescue?

[Greybeard]

Minor signs of use, almost like new!

 that'll buff out

I can see he is telling the truth.

It's hard to see the exact model number and the configuration.
I have a similar model HP that I dumpster dived from work. It's a 20V, 10A supply. It (predictably) needed 2 caps replaced. It dates back to 1974-75.

I'm afraid this unit may require more than just recapping

[golden_labels]

For intentionally damaged equipment this one is an unexpectedly good shape. They must have hired an amateur to perform item reclassification.

[Seekonk]

That is why I only buy equipment that is Certified Not Ready For Use!  Don't buy just random old equipment.



I did once buy a piece that must have been stored next to some sand blaster filled with sand and stored outside.

All you need is a hammer.

[xrunner]

I can fix that.

[squadchannel]

Me too!

Was thinking to buy it just to punk UPS with a "damaged shipment" claim. But that would just make trouble for some random driver whose life's already hell.

Second thought, I've been through this experiment numerous times (against my will); and they never did anything at all.   

Never mind.

If I were in the US, I would buy ..

99.99% certain the transformer will need a rewind, as it's right below where it took the impact, the PCB might also be crushed/cracked below this transformer.
The panel meter might be OK, the bezel falling apart is common for these, surprizing the terminal posts & rotary controls aren't smashed.

How's the saying again?

"When all you have is a hammer, everything looks like this "

[Stray Electron]

   That looks like some of the stuff that I've received from UPS!

For anyone that hasn't worked on one of these, they weigh about 30 lbs. The PT spans the middle (the CG is below where they put the handle) and is sandwiched between structural bulkheads that subdivide the chassis, like a submarine hull. It's literally built like a ship. Merely dropping one off a tall building might dent the corners, but it wouldn't do this. You'd need a hydraulic crusher or a powered drop hammer.

So yeah, I'm pretty sure it was intentionally destroyed.

[golden_labels]

I have little doubt it’s intentional. But it’s also very little damage for this kind of procedure. Whoever did that, forgot to apply the sledgehammer treatment to connectors and knobs. Sloppy job!

[Seekonk]

I never did this personally, but where I worked the equipment had to be destroyed in order to take the write off. Technically that looks destroyed.

   I once bought a big box full of US Army surplus HP-71 calculators at an auction at Ft Hood, Texas.  Somebody thought that they needed to be "de-milled" so they took a hammer and broke the LCD displays in them but they left all of the US Army proprietary ROMs in them.

[golden_labels]

Another sad example.

That sounds not like protecting military secrets, but — the same as above — reclassifying them as trash. It’s a common practice (+ this post of mine for some background; + two related Dave’s videos below).

[5U4GB]

I can fix that.

I think even Mend it Mark would find that one a challenge.

I believe the description said 0.5 A output.
My unit is 10A (can go to 13A)
I doubt this unit would weigh 30 pounds.
My unit weighs about 30 pounds.
The transformner in this damaged unit would weigh significantly less and likely be substantially smaller.

Look again. The victim is (was) an HP 6291A, 0-40V and 0-5A. The 6286A is the 0-20V, 0-10A variant.

But I stand corrected, datasheet says 11.3 kg (25 lbs). I could have sworn mine's heavier....
