First oscilloscope I worked with at my first job, 42 years ago. Even though it was just 10MHz, it has very trustworthy. Beautiful, bright and sharp trace, and all switches were very snappy and given a great click and feedback. The silk screen of the panel was very clear and controls were very well positioned.

It was my first oscillocope when I was 17, still working but out of specifications.

Great time for this to come out. I just got my hands on a slightly older iteration of the D61A with the tabs on the back for trace rotation, and ive been working on disassembling and cleaning up/restoring it. Is the crt not too far forward on yours? In mine and in the service manual it seems that the screws should slot into spots in the tube shield before being clamped down to be able to rotate it properly. Yours is certainly in nicer condition than mine, which seems to be one of a few that were very well used/loved in a lab of some kind

Low hour set it seems. Lucky and nice.

I normally clean stuff before i make video , if I dont do this they look too terrible to photo, I also do it to make stuff more nice to work with
