Analab Type 1120 Oscilloscope

I generally try to focus on Tektronix scopes, but this showed up locally and looked too interesting to pass up.

The orange screen piqued my interest, as I suspected it might have long persistence P12 phosphor. The longest setting on the timebase is 50 seconds (full screen, not per division) and there’s a setting to use an external capacitor for an even slower sweep.

I spent a lot of time just cleaning all the knobs and faceplate, but I think it was worth the effort.

And there it is, that nice yellow-orange trace.

The manual was available on eBay, so I purchased it and scanned it.

More on this later (maybe), but for now I just wanted to get this post up to share the manual & photos.
