Trying to find a video

[Oj0]

Hi guys, I'm a long time channel subscriber but new to the forums

I'm trying to find a video Dave posted some time back, but I'm very vague on the specifics. I think it was a teardown video (Dave definitely opened the unit), probably of an oscilloscope, which MAY have been an HP. I think it was an older unit, as it was absolutely crammed with PCBs - almost (if not) one for each plane. That's about all I can remember

Any help finding the video would be appreciated!

Searching "eevblog hp oscilloscope":

This one maybe?

Woohoo, a reply from the man himself

I've done some extensive searching but can't find it, the video you linked is one I came across but there aren't enough PCBs and it's too messy. I *think* the one in question had very tidy PCBs on the bottom, left and right sides. I may be horribly wrong about it being an oscilloscope or even HP, I saw it a few months back when I was doing some SERIOUS catching up and watching 2-3 hours of your videos each day.

The more details no matter how small could help us...

Roughly how old did the technology look - was it through-hole, surface mount or a mix of both?

I'd have guessed "EEVblog #790 – Lecroy Wavejet 354 Touch Oscilloscope Teardown" as that thing reminded me of a cubesat  when I saw it, which might fit with your one pcb per plane (assuming you meant 3D plane)?

I was thinking maybe the HP 35670A Dynamic Signal Analyser that has all the frazzed op amps...
Dave, I take it you still have never gone back and tried to fix that puppy? 
I'll bet it can be fixed with a full-on op-amp replacement campaign on that board... lol

Or perhaps the HP 1740A if it really was a scope...  Not that many boards, though, but a few.

In addition to drussell's suggestions, perhaps the LeCroy 9384C?
