Bei dieser Röhre sind nur die Horizontalplatten für asymmetrische Ablenkung ausgelegt.

Die Vertikalplatten müssen symmetrisch angesteuert werden, wie man es auch in der Schaltung sehen kann.  

Die hier gezeichnete innere Verbindung zwischen g2+4 und einer Horizontalplatte existiert nicht und muss extern hergestellt werden.  S. a. Oszillograf Grundig_w2_6023.
