Has anyone taken a look at what's inside these things? https://www.ebay.de/itm/0-9999-9-Ohm-Variable-Decade-Resistor-Resistance-Box-Physical-Teaching-TooY-tq/353276507282

If the switches were good, I'd buy one and swap out the resistors.

McBryce.

I can't believe the switches will be any good at that price. I am tempted to get one to investigate though.

I suspect they will be plain brass contacts with some highly inappropriate lubrication (if any) that causes extremely inconsistent results.

Maybe brass plated aluminium lubricated with lard.


You know, there *are* people around here that offer quality  decade boxes (from a slightly older vintage) around here, right? :popcorn:

boxes?   >:D    :)
I can see one with four ranges in your shop..

Edit:
BTW, Tony reviewed a cheap four ranges resistor box:


Inside is a PCB and the switches are made of the copper traces of the PCB and copper sliding contacts with possibly "some highly inappropriate lubrication".   :horse:    :-DD

One in worse condition sold last week and made nearly double the start price of that one. Someone please outbid me as it's only a 10MHz counter.

@Zucca, PA0PBZ and the others:   my pleasure!   :D

Those naughty little thingies sneaked in somehow. I guess, they are kind of being up and running and that's perhaps the reason for R&S to mark them with a red dot.   :-DD   Glad, that you've enjoyed it.
"being up & running"...? ???

I know it's just a lost in translation thing... but now I need to know more.  :P

 :popcorn:

Well, they have eight legs and a round, hard carapace...

My Christmas care package from BU508A arrived today, thanks!

I can reveal that mine also contained stowaways, nimble little critters, born in the late 1980s.

That was EXACTLY what I was thinking would be in those Chinesium bricks. Voltage capacity in the low dozens, I'm certain.  :P

Yes, a nice display like this, on my first frequency counter. Picked it up for £5 at a hamfest. I've since got a nice reciprocal counter and a (14 digit?) "frequency microscope", but nothing as pleasing as these glowing dots.

Someone is selling one of them with a bunch of accessories and leather case on ebay at the moment. I don't have the link handy at the moment though.

Edit: yes I do and I'm an idiot - it's their DMM system: https://www.ebay.co.uk/itm/HP-Multimeter-system/324387956221

I have one of the 34740A DMM displays one like that, with the 2802A thermometer input module, warning contains a Sprague 109D.



Also have a broken 34750A with damaged DMM input module (circuit board split).

Yes I saw that too, and though it looks very nice, it's way too expensive.

OMG the worst packaging effort ever?

At the other end of the spectrum, I once received an SD memory card from an eBay seller that was packed in an even larger box than yours, complete with padding!  :D

It's Philips. It'd have fallen to bits if it was packaged properly anyway!

It likes it's local climate, so they stay well conserved here... we have more rain then UV and most of us keep them dry.

The water cooling system seems to have survived its little stuck solenoid incident, but as my running of it up to now only was a test run before wintering, I'll still go ahead and take it offline, so I can fit a proper expansion vessel to it.

I can't say or write "vessel" without thinking of Chekov in Star Trek The Whale Movie (i.e. "Star Trek IV: The Voyage Home"). Permanent damage, that.
