Here is a thread for reference:

Unfortunately the pictures are long gone there.

I have my monitor in the vertical position, but I will describe it in the standard horizontal position for easy reference. The screen bends in at the very top, and the top 1/4" or so slants to the left. The bend is kind of a trapezoidal effect. There is also a lighter streak horizontally in the middle of the screen. It is barely even noticeable. I did a tube swap from a TV. Direct swap because the yoke was exactly the same ohms.

I have tried to adjust the distortion out and can make it a bit better. The light area kind of looks like magnetism, but isn't getting better with repeated power ups/downs over a few days. I also did a cap kit with no change.

Back to that thread, that cap value Ken talks about intrigues me. Without the pictures though, I have no clue if his problem is the same as mine.

I can take pictures if that helps.
 
Photos are always welcome. I'd go on a limb and say for mystery things like this that are hard to describe as "required".
 
And despite how "perfect" the TV yoke is a match for the original, you may never know whether your issue is related or not without putting the original G07 yoke on it....
