Playing with old CRTs always generates lots of questions. I have tried to answer some of these in a series of two videos on the history and construction of common television electron guns. These CRTs all employ electromagnetic defection provided by scan coils or yokes. The videos covers both Black & White and Colour tubes and tried to show how to identify pins on the base when no CRT data sheet can be found.
The early colour CRT gun is shown here but Mullard released an excellent film on the manufacturing of this tube, ‘It’s The tube That Makes the Colour’ and it can be seen at: youtu.be/0Qd4IX3wpZk
In this second part the parts of an 'in-line' electron gun is dismantled along with some common pin connections.
Warning you need to be very interested in electronics and cathode ray tubes to watch these two videos.
