I have a not-quite-dead (no output but powers up) HP 8640B signal generator on the way from eBuy to join the queue of 'things to repair in my spare (so called because I have so little of it) time'. I also got the two volumes of the service manual for the 3561A, so I'll be digging further into that soon. Fun, fun!

I use to dream about owning an 8640 I have many hours using one, shourd be a fun project.
I picked up an HP Universal Counter HP-5315B for $40 US, clean inside fully functional.
Another 8060A, another bobby dazzler:
Actually, over the last 16 years, this trusty old brick was the only multimeter I had at my desk at work. Just like two months ago, I finally decided to order a 87V at work (owned one at home for some years now).

Sweet! Looks nice, and you can't beat the price, especially for a working unit.

I guess buying a second one is cheaper than buying the spare parts after a crash?

Or nothing left to re-use. (Isn't that normal after an airplane crash?) We want to read the story and see pictures!
Just ordered a Ti 84 Plus CE Calculator, my Sharp EL-512 from 1984 is starting to show it's age and the buttons are starting to fail. I've wanted a graphing calc for quite a while too.

I bought 20 of these about two years ago and now have run out. Use them for filters and little function generators and the like. They solder up to the edge on a PCB or proto-board, at least the proto boards that I use, and are super convenient and compact. Graduated to the big-boy package:
They are $1 or more for AMP or Molex branded ones at Digikey. Much better price here.
A lot of cheap RF connectors have brass instead of beryllium copper as the centre. Fine for the first couple of connections, but after that they're useless.
I bought a second one of these a week ago

Nice. What happened to the first?
pilot error
Or as we said in the Air Force, was it a short between the headsets?
It was an effortless upload on my phone, chill out

Those are the Bee's Knees...
The power supply I picked up Saturday that has been riding around in my friend's trunk since then...
2X 36V 1.5A
$25.00 US I do need to see how clean the output is, it is a bit long in the tooth.
But..
The price was right.
Wow, Sue, quite a catch. That should go in the test equipment "scores" thread.

The description says "gold", but they mean 'gold colored'. Chances of that being actual gold plating are very slim.
Anyone know what that 'gold colored' plating on cheap RCA connectors and such is actually made of?

It should, next time.
It is old and I may change out the rectifier since it is selenium, when those things fail they emit toxic fumes.

I buy these by the thousand for production, they work out at $0.20ea. I also use male versions for inline prototyping filters. I'm not sure how well they work beyond a couple of GHz but for the application I have them in they are fine.
I visited the new local surplus store today and grabbed 2 HP LP2275w 22" LCD monitors and 2 VGA to DVI adapters for $91 USD with tax. One had minor scratches on the screen that aren't visible when the monitor is on. Both have no dead pixels and are nice and bright. I had a 22" and a 19" LED monitor on this computer but the 19" has gone to the spares shelf and the 22" LED has replaced a 17" on my workbench. It is nice to finally have matching sized monitors on this computer.
