HM203-4 analog CRT oszilloscope repair

In this Video we repair my old Hameg HM203-4 oszilloscpe from the eighties which can't show a properly focussed trace anymore. And i also forget to lock the white balance on the camera to make cuts look extra bad :P I've been given this a long time ago by my physics teacher. Playing around with it is what got me started with proper electronics projects. So it has quite the high sentimental value for me :D Service manual for the scope can be downloaded here, incase you want to have a look: https://cdn.rohde-schwarz.com/hameg-a... https://cdn.rohde-schwarz.com/hameg-a...
