ABSTRACT:
In a method of manufacturing a colour television display tube, a reference system is used for adjusting the various components of the tube relative to each other. The system fixes the deflection centre and the electron-optical axis of a deflection device, provided afterwards on the tube, in an early stage of the manufacturing process of the tube. The adjustment of the components is carried out while being referred to the fixed deflection centre or the fixed electron-optical axis. The method simplifies the subsequent positioning of the deflection device on the tube.
