This high school junior has a better collection of vintage test equipment than you do.
I know how much you "vintage" engineers out there like to talk about old test equipment. Yes, there was a time when all test equipment was analog and had a dedicated knob or switch for each function. You may even still have some old test equipment for your home lab, and it may even work. But I doubt you have as much test equipment as a high school junior.
Daniel Sheen and a small portion of his vintage test equipment. This room is a museum, and most of the equipment works.
On March 17, I visited the home of Daniel Sheen, who has amassed an impressive collection of vintage test equipment -- oscilloscopes, spectrum analyzers, voltmeters, and signal sources. Best of all, nearly every piece of equipment works. Some worked upon acquisition, but others required Sheen to repair them. He also has a collection of manuals, which often provide schematics.
You can see his collection, both in photos and in a video, at EDN, a sister site.
