The beauty of old and new measuring instruments and their parts. - Click HERE for Original Thread

This would be a thread to post some picture from lab equipment you have, preferably with the nice rare parts inside, showing the effort made to achieve best performance.
I opened an old Philips DMM last week and was happily surprised with the exotics of the components inside. Here’s my contribution.: Philips PM2424 DMM.

The white cubes are relays of a kind I never saw before. Wired in parallel you can see some parts having a little copper wire running through them and soldered to other parts in the circuit:

Precision resistors and early SMD transistors. Look at the combination of point to point and PCB:

Those white relays look like reed relays. Is the center a glass tube?

Yes, and although I have the schematic, I haven't got a clue what the paralleled components with the wires are.

Oooo, I might just have to open up my Tektronix 475 for this thread. And since you're counting old I could pop a few of my Eico 377 signal generator. And Heathkit IO-10 scope...hmmm....

Please do!

Only six screws hide the splendor of Fluke:

I dont own one and had a tough time finding a decent picture of one, but I've always loved the look of the Leeds Northrop ballistic galvanometer.

Rather expensive when new ....

Does this count (tek 7A22 diff input amp) ?

I wish i had one...

Today my TEK7313 storage scope arrived and i play with it at the moment using a 7B53A and 7A16.

Ok.. I probably won't take apart the Tek again :rolleyes: and the Eico is downstairs so here's my B&K Precision 3026 5MHz signal generator.

That was the top circuit board, this is bottom. Yep, the only big IC is the display driver, everything else is logic and op-amps. :bigeyes:
