The invention relates to an electron beam tube for viewing color television images in the vicinity of the screen 3 has a substantially rectangular color selection electrode is arranged, which is in the tube, by at least three preferably streifenföraige Stutzträgertr supported iot, each on the one hand at the Umfoni; the color selection electrode > operated and on the other hand by an in the support point provided for the R pipe wall is supported »The Invention relates in particular to the type of construction Support members door the Parbauawählelektoda.

In known designs, such support members consist of a resilient strip with uinen End attached to the perimeter of the Parbwahlelektroac. And on the other ünae uit an opening for receiving one at the "

The errors that occur as a result of the asymmetrical distribution of the pipe members over the circumference of the ilask can be reduced.

Here, this arc produces not only a Bewegungekoinponente toward the phosphor screen, but also a movement component in a direction perpendicular to the ear socket. The whole shadow mask is therefore not only moved a little towards the fluorescent screen, but also shifted a little, so that the center point of the screen remains on the axis of the face and that due to the asymmetrical displacement of the holes in the saw Other errors occurring in the mask
