I'd guess too. In central and eastern Europe, 7 to 3 is the norm but nobody pronounces it that.

Yeah, that kind of special treatment, absolutely. But once in a concentration camp, they'd be just another subject with a number, albeit likely a lower one.

Well, you have a lot more experience than I do. I don't think I can provide good advice but the idea of another circuit borking it is interesting, I'd put voltmeter(s) on the supply voltage(s) of the deflection circuit and check for changes.

Please don't call the unit "CRT", it's weird to read phrases like "when the CRT is apart" because you can't really make a tube work again if it's been apart.

However, it makes me think if one could smash all tubes in a vacuum tube TV in the vacuum of space or one big glass chamber and have it still working. Or build a monitor into a tube that looks like an overly long CRT but just needs power and video. Maybe even include an IR remote receiver for digital picture adjustment. This is way beyond what I will ever be able to do, though, and there is little reason to make this gimmicky thing that is worse than Philco Predicta (TV model line with CRTs outside cabinets) in almost every way.

Also, I think there is a bit of a mistranslation: the Catholic Church most likely does not consider material poverty a sin, they meant "being poor in spirit", or lacking any good values.

I assume datasheet websites just have pages for every combination of 3-12 alphanumerics to appear in search results, and then use shitty fuzzy string matching tactics to find "most relevant" items. It would help if they managed to extract package marking codes from datasheets so you can find SOT-23 parts by their 2-3 character codes, or whatever obscure system used by individual IC manufacturers. I think they have resources to make the experience way better but they prefer to turn high profits. Personally, I would not mind trying AI (not neccessarily a LLM) for the data extraction but I'd be cautious and only release it if it is decently reliable (but I know they wouldn't bother with that).

Pretty sad that a technical manual for the monitor was most likely created but just not digitized in a way you can find. Intermittent faults are very hard to diagnose. What I would try:

  • I assume you've cleaned the potentiometer, which is also easy to check with an ohmmeter (mind the polarity or desolder it to protect the rest of the circuit).
  • Poke the circuit board with a non-conductive object to find loose solder joints or components with bad contacts inside. If the fault is not mechanical, it might be an overheating component.
  • Try adding a fan temporarily to see if the fault appears later, or use a thermal camera to find semiconductors that might go near their threshold temperature (150 °C for the silicon die).
  • Find points in the horizontal deflection circuit where voltage or waveform changes as the fault manifests.

Made in 1936 and Kafka died in 1924. He would probably have died in a concentration camp if he lived to see this. Nazis did not give special treatment to Jewish writers, for example Josef Čapek (✝ approx. 14 April 1945 Bergen-Belsen). Still, there must have been other bizarre filing systems in his era, a multi-story vertical conveyor belt of filing cabinets is used in some town halls to this day.

Watch on YouTube
Here's a video of them in action - you can see the Nazis tried to create popular high-budget movies despite the war costs. They weren't very fast even back in the day and now that they are only used for historical records, they probably go even slower. I'm pretty sure their usage is very restricted and still they likely needed an exception from the European equivalent of OSHA.

Datasheet websites do that a lot. If it's PDF.js, Firefox's PDF viewer (or a fork of it), I just right-click to "Show only this frame" and it goes fullscreen. It might have shenanigans such as disabled printing but you can press Ctrl+Shift+E and reload to check network activity for what address the PDF is loaded from and save that.

The worse ones are PDFs that exist only for SEO and contain nothing but keywords and a link to a paywall.

Scientists in 1985: "This data can now all fit on a computer thanks to CDs. Get a few of them pressed at Gramozávody Loděnice every year and keep the index plus updates on a HDD or tape."

Scientists in 1990: "With CD-R, you don't have to pay a fortune to have a few copies of the database pressed every year. You don't need the magnetic storage buffer either, updates can be written on the disks."

Scientists in 2000: "Screw CDs. Many-gigabyte HDDs are decently cheap. You can store full scans rather than transcripts."

Scientists in 2010: "You can afford terabytes in SSDs now, and keep a few copies off-site for backup, all in a cloud solution with access from anywhere with less latency than the HDDs."
