An ugly but working HP6060B Electronic Load
AMR Labs:
So among my e-pay expeditions came across this HP6060B Electronic load. It was priced at $750 and described as a "Signal Generator" guessing the seller got confused with a similarly numbered model 6060B Fluke generator. At the time a few other listed HP6060Bs where at $900 to $4K+. Anyway after some months of having this on my watch, still no takers and I saw the seller came down to $350. Since the unit looked a bit neglected and dirty, plus some obvious minor aesthetic issues offered $200 and the rest is history.
Unit arrived at least well packed, it ought to be as for the first time I ended up paying a bit more shipping than it was shown on the listing. It went from $76.60 but changed to $99.10 at checkout. Not sure what that was all about and have to slug it out with ebay as seller denies having raised his shipping cost last minute after accepting my offer.
Top cover was grimy and dirty, some dents and scratches here and there, and inside all looked ok but quite dusty. The one surprise was that one of the binding posts in the back is missing its cap, broken off I suppose, one thing that conveniently was not shown in the listing pictures. But at least it is still functional. So I am on the lookout for a replacement post, if anyone has one for sale please contact me. HP part number is 1510-0134 and since I would also like to implement the front panel binding post option, I could use 3-4 of these. Keysight lists them as "ordeable" but out of stock. Nothing else out there but the typical aerospace parts sellers that want you to send them a request for RFQ. Yeah right.
Anyway, cleaned up the insides, also disassembled the front panel, and since some of the keys where not working consistently took out the membrane and cleaned the contacts. Put everything back together and the things works perfectly. Strangely the key on the right top ("Input ^") has completely lost its face as if it was shaved off. But at least it still works.
Ordered a rack ear/handle kit to fit, as this unit will go into a 12U rack enclosure cart with casters, above a huge and heavy HP6268B power supply that I just restored.
See thread here: https://www.eevblog.com/forum/testgear/hp6268b-restoration/
Also thinking to install in the same rack my HP3457A DMM that does not get used much, but I figure it will look nice mounted there.
So if anyone has one or more of the heavy duty binding posts used on this load, and willing to sell, please let me know. Don't even need new ones, I'd be happy with used ones as well. Or as an alternative if someone might know the original manufacturer of these, or even an OEM part number, that would also be very helpful. On mine there are absolutely no markings or numbers. And the service manual being from the 90s no longer includes the detailed parts supplier list, just so now Keysight can sell you an ordeable but out of stock part.
AMR Labs:
I would like to add the front panel binding post option to my 6060B, and have secured an additional pair of these humongous posts. But it seems that beyond drilling out the two holes in the front panel to secure the posts there is also a plate that looks to be made out of plastic and that goes on the outside of the panel in order to provide additional mounting rigidity. I was wondering if someone that has a 6060B with the original front panel post option could confirm what material this plate made of, is it plastic or perhaps aluminum? Also the dimensions would be nice to have, including if possible the thickness of the material.
I am aware there is a Gidhub page of someone that did 3D print this front plate, but it does not seem like a workable solution to me. First of all it does not really look too well aesthetically speaking, and secondly I have no way or interest of 3D printing something like that anyway. In any event would rather find a piece of the appropriate material, and cut it down to the proper size.
And it goes without saying that if someone happens to have a 6060B parts unit and would like to sell that panel, I'd be of course very interested. I would even consider buying a second pair of binding posts if also available.
Thanks for any leads.
Bud:
Unless you intend to mount the unit in a rack, to avoid drilling the front, you could make an L-shaped bracket and fasten it to the mounting holes on the side panel, with binding posts wired to the back of the device.
AMR Labs:
Yes unit going into a rack. I was actually thinking of using a 1U plate to mount the posts and wire them into the rear posts as an alternative, but giving it a try to get them on the front panel before deciding how to ultimately proceed.
Thanks.

I have just bought one of these and would also be interested in posts for the front panel. Please post back if anyone finds a supplier of posts :)
