I've seen some sharp CGA images on these forums now and again while my 5153 doesn't look so good. I've tried adjusting the convergence and screen focus as best as I can, but I can see they need more work.
Are there any other issues that might affect sharpness that should be corrected first?

The image is a bit narrow as well, another challenge to to tackle. I'm certain the PS voltage is correct because I replaced the original 120V item with a modern open frame industrial unit so I could use the monitor on 230 VAC.
