Hey guys I replaced a few of the caps in my BK 1077b and after adjusting the vertical a little bit I was able to fill most of the screen. Do these usually fill up real nice or is there usually gaps like I have in my picture? If not I can't find a good schematic for the 1077b I find plenty for the 1077 and judging by the fact that the filters are different I don't know if I can go by the rest. What caps should I go after to get full vertical deflection?

There should be gaps. Do you have any of the test pattern sldies for it? The raster should be the same size as the slide, with a 4x3 aspect ratio. You have the height turned up too much.

I do have some slides, should it be just wider than the slide? I'm hoping to get some BNC connectors so I can try and make cables tomorrow and see if it works.

The slides I have seen have black borders all around. The raster should just fill the clear area.

I got it working pretty a well now. (The horizontal at the top of the screen is a little off on my other pattern generator too) My only problem is the picture is a little too far to the right. I can't seem to find a way to adjust that.

If you have or suspect vertical troubles, check the 3.3 Meg resistors for increased resistance.
