If you like this kind of content, I highly recommend checking out the Youtube channel 'The Signal Path' [1]. It has some fantastic technical teardowns and repairs of instruments, including really high frequency equipment.

You probably already watch him, but Marco is also great when it comes to similar content (he loves his multimeters) https://www.youtube.com/@reps

they're zooming in on different axes of the oscilloscope, though. tsp is about picoseconds, reps is about picovolts

I like bigclive. He takes apart cheap electronics from eBay.

Curious Marc[1] works on a lot of old HP test equipment, and he’s also a Silicon Valley native, frequent contributor to the Computer History Museum, and his channel features an HN regular, Ken Shirriff, who can reverse engineer everything from vintage Russian Soyuz components to uncapped IC packages.

Woah, thanks for the comparison. I'm a huge fan of the signal path and marco reps, but I don't think I've gone that far down the volt nut path yet. Maybe I need to fix up a broken 3458a for my next writeup :D
