Does old test equipment really ever become truly obsolete?

What's wrong with that bridge? If digital indication provides better accuracy by its own? The only real problem is that the things like that are lasting too long to be profitable for manufacturers

Aldo22:
The fact that you can still "use" old equipment (if you have nothing better) is one thing.

What is repeatedly recommended to beginners in this forum is to buy a 30-year-old 20MHz CRO because it is "better" than, for example, a Hantek DSO2000 for a similar price.
Is that nonsense or can you say that with a clear conscience?
I've never had an analog scope, that's why I'm asking.

YES equipment do get obsolete from pro use in a company,
then hobby dudes and radioamateurs score them and continue to use them for another 10-20 years,
then collectors get the stuff to play with, and store for another 20-40 years,
when they die, sadly their kids take it all to the dumb..
I am the missing link just before the dumb,
need prof : search youtube for : oz2cpu teardown
I get car loads of instruments in every week from people who just want to get rid of it,
better give it to me, or have some of my many friends come pick it up for them.

coromonadalix:
yes and no  for  mentioned reasons,  it depends of what you need to do ....


oz2cpu   i envy you   loll    i would like to receive thoses thingies  loll

aldo22    i had analogues scopes before,  phillips  and others,   and at one time they where pretty good ..
              BUT now technology evolved,  lcd screen got very good and fast, DPO technology  helped a lot
              if you had some Fluke portable scope  you'll understand what i meant   loll  it was very crude


I'm still using 20 years or more meters,  34401a  34410a ,  some Beckman Industrial meters / Wavetek ...  still going strong, and never blown a fuse in them

Some of the old stuff can still be pretty darn good, really depends,  still using old TEK TDS 7k series ... at least 20 years old  ...

Some OLD Gossens 28s 29s meter,  nothing recent beats them, and old psu's,  some where build like tanks, weighted a ton  IE:old Kepco  52 pounds, and a Kikusui (almost same specs, newer tech 25 pounds loll)


really depend of the needed usage,  some will last a life time, others dont

Quality as taken an huge drop, now  it's now more like :   use them, they fail  = trash them

Laugh on me, but for low resistance measurement, I trust this old bridge more than my Fluke 189 because it's a specialized tool and there is absolutely no magic inside, while the Fluke is a general-purpose multimeter. And BTW, the polyurethane foam on the battery compartment cover is disintegrated by now. So ridiculous. Also, I had to replace the supercap because of leakage.

As for the beginners, I'd already mentioned it somewhere here that when I was a schoolboy, I found a huge oscilloscope in the garbage area of the yard. I'm not sure if it was in perfect working condition or my father provided some initial help. But to my memory, it was somehow working from the beginning. It was of pure tube type and sometimes I was bitten by high voltages. That was OK, because on the other hand, it tolerated all my mistakes (it's difficult to get a tube electrically damaged). I could experiment with changing the schematics and to see the effects from this on the CRT screen. So it was perfect for learning. Not sure if any modern equipment (of any price) can give a beginner better insight in electronic circuits
