Thanks for all those nice pictures. I've forwarded the URLs of your Datron 1071 to bitseeker for his list.
And for entertainment reasons, here is the list of the repair videos from FeedbackLoop of his Datron 1071.
#47 - Datron 1071 7.5-digit multimeter repair
#48 - Datron 1071 display replacement part 1
#51 - Datron 1071 display replacement part 2
#90 - Datron 1071 LED display
#92 - Datron 1071 LED display followup

There are some more to come! I also realised I'd posted them full size so I just went back and edited my posts to change the
images to 500 pixel previews. They're still clickable for the full size versions.
I remember watching feedback.loop's videos. What a shame he ended up with a duff display. I've since bought a very basic 1061
with no options just so that I have a parts mule with a spare display and some of the unobtanium components if I should ever need
them.
Just like the Solartron 7075 that I have, the gas discharge displays are so nice to look at, particularly if you have eyesight which is
as crap as mine is becoming.

On the (Woodworking) Bench This Morning: Anniversary Project Table
--- Quote from: mnementh on July 13, 2022, 09:04:23 pm --- I ordered the "Sanding Discs by the Foot" packet from Amazon... free delivery in aboot a week, but it only cost $11. That's less than a dollar a inch! I know a lot of guys and gals who'd gladly pay that! >:D
Anyhoo... it has discs from 40 grit up to 1500 grit; so far I've used one 320 grit disc and have all the runs & orange-peel spots smoothed out. Next will be finish pass; I'm thinking 600 grit. Might do it tonight, but likelier tomorrow AM when it's semi-cool out there.

SO close...
Another couple rounds of sanding with 600 grit, another couple coats of urethane. The runs on the edge I could live with, and the few fisheye spots are very ignorable... but there are a good half-dozen bristles stuck in this coat, which really pisses me off as I splurged for decent name-brand brushes this go-round. :rant:
Right now vacillating over whether to try foam brushes, or cheat and get a rattle-can of oil-based urethane for the final coats. Hopefully I'll be able to get those bristles out just sanding with 600 grit.

What could it be?

It's a General Radio 2220 Bug Hound. Used for tracing shorts and opens in PCBs and wiring. also good for genearl circuit tracing.
Unlike similar tools like ToneOhm and the HPP current tracer probe it uses AC signals and a phase sensitive detector. I'm looking forward to using it in anger.

So non-contact, or just very tiny current so as not to blow up stuff like the ShortSqweek and Huntrons?

Both.
Non-contact probe with LEDs to show current direction and contact with +- 50uV or 500uV

Ooooooh... does indeed sound like the PCB debugging Holy Grail. I can see why you're so pleased to find one. :-+

To New Jersey? That's a bit harsh. (Not that I've been there, but the reputation I've heard of is not stellar.)

In other news, frozen pigs just flew out of hell… it looks like it actually works.
Have ID’ed the probe sensor doesn’t work properly on one of the channels but that’s an easy fix. Might even work with a clean.

Now now, no criminal damage... the same effect more or less can be achieved with small bits of wood ie matchsticks, jammed into the valve. It lets all the air out, but doesn't damage anything. Or you can use a Schrader tool to loosen the valve core, to the same effect.
--- End quote ---
That still counts as criminal damage.
--- Quote from: https://www.lawtonslaw.co.uk/resources/criminal-damage/ ---The damage caused as a result of the offence does not have to be permanent. As long as the damage caused affects the value or performance of the property, this is sufficient to be classed as an act of criminal damage.

If there's any work involved in correcting what's been done, or if it [temporarily] affects the ability to use the property it counts as damage.
Letting air out of tyres might even count as aggravated criminal damage as it introduces an element that might cause physical injury to a person.

Mmmmhmmm... so inconveniencing someone wealthy enough to own a car is criminal and prosecutable... but destroying lives and making it impossible for whole segments of the population to house or feed themselves, much less own a car, is okay because it's monopoly corporations and politicians doing it, so is just business as usual.
Does cast a stark contrast on the concepts of High Crimes and Misdemeanors vs The Golden Rule, doesn't it? :-\
EDIT: That actually is even more perverse than I originally thought. Consider this all-too-possible scenario:
Entitled dickbag parks in a handicapped spot repeatedly; often enough that someone who actually has the permit notices. Said victim calls the cops and lets the air out of his tires so he can't get away before they arrive. At worst dickbag receives a ticket he can probably get out of if he hires a lawyer; handicapped victim actually faces criminal prosecution and jail time.

we are fucking doomed.
