Re: (OT) Curious about DuMont Type 233 Giant Screen Oscillograph
One of my prized possessions was the HP 143A Oscilloscope mainframe, which took the various RF and IF spectrum analyzer sections that the 141 took. The screen was 8 x 10 inches, instead of cm. Unfortunately one of my plug-ins failed when I turned on the 143A, and I suspected it was a power supply problem in the mainframe. And besides, it was just a bit large to take along when we moved to Hawaii.toggle quoted messageShow quoted text
It was, however, quite impressive!

Interesting. Are there any scans of that datasheet?
Good luck finding one...my gut feeling says that if any exist it'll be in someone's estate.
