Meanwhile I have got full width with two changes:
- added a capacitor 20 nF parallel to C159
- changed R184 to 150 Ohms.
But this is not the final decision. I assume that the 6BG6-G, which I tested well, does not provide enough current. I will try to get a spare tube.
Here is a screenshot. Note that the screen color is blue due to the indoor white balance of the camera.
