How can I adjust the vertical position of the image on my Midway Space Invaders? The image is shifted to far to the left. I'm looking at the manual and the schematic (and the chassis) and I can't find anything that looks like it might move the image.
 
Have you capped the chassis yet?
If not, those caps are decades old and should be replaced.
If you have already, try vert. lin. and see if that has an effect on the display.
 
Thank you, Dez and Jetusenet.

I have adjusted the tab around the yoke magnet and it makes only a minor difference, mainly in the straightness of the image.

I did have the chassis capped by Chad at Arcade CRT...he did an awesome job of bringing a dead monitor back to life. I've only just completed fixing several other issues with the game boards so now I just have to get things adjusted properly.

Thanks for the suggestion about the vertical linearity adjustments. I'll see if adjusting R263 and/or R257 does the trick and I'll report back. Thanks again for the quick suggestions.
