Glad to see my post brings a nice trip to you.

From the comment sections, it appears to me that Hacker News has no shortage of hobbyists and professional electronics engineers, but when I search relevant terms like "Tektronix", "oscilloscope", "spectrum analyzer", or "SPICE", there's no much information here, only two or three top articles. I guess it's unfamiliar to the Silicon Valley CS majority who doesn't have enough appreciate of hardware engineering. I'll try to post more of them in the future.

Absolutely go. I repair these scopes as a hobby and the people at the tek museum have been endlessly helpful. Repairing old tek designs and reading the schematics has made me a much better analog engineer.

Hey I'm in Cedar Mill and used to live practically across the street from Tektronix. My email is in my profile if you want to get coffee or check out the museum together. :-)
