I have got two old 1970's vintage scopex oscilloscopes that were part of a collection of equipment I was donated, some of which has already been shown on this channel. I thought I'd see if I could repair them even though they are very old and not worth much. Both scopes had faults with the timebase not running.
I managed to repair the 4D10 however the 4D10A was scrapped due to it having been modified and I'd spent a long time on it.
Hopefully this video is useful to someone who wants to repair their oscilloscope.
