A post in the repair board spurred my memory about an episode of the old Thunderbirds Supermarionation show. In an episode they use some real oscilloscopes, and it appears that they might be Telequipment models (see screenshot). Anyone agree?
Banana post inputs, yes maybe a very early Telequipment.
After small search: Serviscope S51E......or similar.
That brings back memories ... showing my age, and referring to things that no-one of a certain age, or from the UK (or some commonwealth countries) will know what I am talking about ...
My first job out of school was an apprenticeship with Rediffusion (a sort of cable radio/TV company).
On of my tasks was repairing the repeaters that shuffled the TV signal around the network. Basically just HF amplifiers (yes, the TV signal was carried on HF carriers!).
Once repaired, the filters had to be checked/adjusted to ensure that the response was flat and the bandpass was correct.
This used a sweep-frequency generator and diode detector. The sweep voltage triggered the oscilloscope, and the detector output fed the Y axis. An extra graticule was added with the expected response shape for specified 'scope settings.
I spent a lot of hours in front of that scope - very similar, if not identical to the one pictured above.
Eventually, they acquired a new 'scope. I bought the old one. Unfortunately, it didn't last long. It was pretty old by that point.
