I think this setup has been used for some kind of energy /pulse height spectroscopy, likely gamma spectroscopy.

Super high quality amplifiers - AND A VARIABLE 0-3 KV DC PSU - and a dual 0-1000V!

Unfortunately no ADC or multichannel analyzer. Oh well. I'm happy as a pig in mud!

Don't be sad, I've seen vintage multichannel analyzers - they are a large box, with inferior performance to something you can whip up today using off the shelf part. I can't find it at the moment, but I seem to remember someone did an MCA using a sound card. You can also in theory use a scope with a height histogram (such as MDO3000).

Yeah true. I did get some kind of digital interface in a NIM box along with it, but it's undocumented, built on veroboard and the ribbon cable has just been cut so yeah, might not be feasable. Certainly isnt, i'd think. But the empty box with backplane connector is nice for own DIY's.

Not particularly exciting, but found in an unusual place: a housewares thrift store.  When was the last time you found a Weston milliammeter in with the credenzas and hassocks?   

And yes, it works - I tested it with my HP calibrator.

Some ADCMT / Advantest equipment. There is some fault in R6144 and might be also in TR5834 which was sold as is, not tested. Lets see what will I get

I’m not sure if I need pulse jitter counter that often but one can use it as a frequency counter with pocket calculator

Very nice units, congratulations !

Thanks!

Is that the unit with a faulty 1v range? If so there is a thread on here about units with the same fault.

I looked at it but decided I don’t need it. It might be worthwhile adding your repair to that thread to update it for future users

Yes it is. Thanks for the tip, I will add my findings to that same thread.

Got a nice birthday gift from my wife. Finally the bench will be more organized 😂

The molded carry case has a lot of internal structures intended to hold just this grinder, cord and accessories. Which make the case useless for anything else. I never use them, and in the past have always thrown out the cases immediately, as they are a waste of space.

I tried to recycle one and they wouldn't even take the plastic. Those things are a total waste of resources.

They may not be exciting, but I still like old panel meters. I grab any I come across that aren't exorbitantly expensive. Nice find.

Really glad have friends here, especially on this type of appetite. 

Some eyes candies on what I've scored recent years, and the appetite keeps stronger.

Eakins autofocus camera. I shouldn't have because it's really extravagant for a newbie like me, but I did.

Seeing that it works with my existing trinocular scope is what convinced me. That almost halves the price and means it won't take up any desk space. Stumbled on this possibility on a YouTube video at https://youtu.be/8eqj632svDM

Picked up a Hewlett Packard 6612C System DC Power Supply from eBay for a very good price (delivered to Australia). Cleaned up very nicely, display is a bit dim. Being able to source and sink, I am going to use it for battery charge/discharge using SCPI command scripts in Python. Did a voltage cal and it is bang on, need to take it to work for a current cal.

Bought a few things this morning, this is one of them. Seemed like a good deal on sale for 31% off.

Also bought a Wiha canvas pouch in an order from Amazon.

Also a good idea - see pic -, since my bones
ain't becoming more flexible these days.

Driven by the move from W7 to W10
involving cloning the SSD and retaining W7 just in case.

SSD can almost always blow new life into older PC's, and the higher capacity a SSD is the faster. Just use it as your boot drive if you don't have an NVMe drive in your machine. (I have switched all my machines, even my old 2004 Dell Latitude D620, to SSD boot devices. Older devices like that D620 and two thicc MacBook Pros use SATA SSD, and all other computers use NVMe for something even faster.)

These are one of the best power supplies ever built by HP
The displays always have been more dim than on other instruments, it seems normal on the 6612C

I bought a Qi wireless charging pad today, for my iPhone 8 so I can ramp down the Lightning port usage.

[TerraHertz]

Two HP 3478A 5.5 digit DMMs.
Yes I know they are old, and the displays could do with hacking to add a backlight.


Here are some resources I've found, are there any other good ones?

Looks like you found the good stuff. Getting a backup of the cal ram is #1.

Just got a Fluke 87V, described as boxed, new and unused, for £160.00 UK. It does indeed look as new but the most recent date I can find on any of the included docs is 2007.  Would anyone be able to date it from the S/No, which is 96350419?

One the Black lead there is a manufacture date of the lead. It is not that easy to find but all my TL175 black leads have them. 
With the pcb revision number, meter serial number and lead date you should be able to narrow the manufacture date of the 87V

My latest purchase is a Pace TD100A soldering iron to replace the TD100(plastic one) that came with my WJS station .
The new soldering iron comes with a more flexible and thinner lead and the iron itself feels better balanced.  The lead does not drag the back of the iron down.
 I always felt I was wrestling with the thing.
Some people complained they had heat issues with the old plastic iron, but I never did.

Also waiting for delivery of a spare hakko fx880-1 iron. the hakko fx888D is still my favourite iron even if it has a crap interface just set to 300C  and leave it alone.

HP 8563E spectrum analyzer! 
Should I change my ID? xDDD
