Mac SE/30 CRT adjustment help

[xreactx]

Hey group. My Mac SE/30 CRT image is too far to the left. How do I adjust/move it to the right? I did a quick search here but couldn't find anything... Sorry if this is redundant.

There are two centering rings on the neck of the CRT.

All has been said by Rollmastr, grab one ring or the other and turn it clockwise or anticlockwise.
One will move the image up or down, the other from left to right. Keep in mind that those are probably sealed with some paint and will require to break it first.
be careful, close from the fragile part of the tube, turn the SE off first to play safe, once done turn it on and adjust the screen.

If it was OK when you had the CRT installed in your old SE/30 case, I'd loosen the CRT mounting screws and physically move the CRT over a little to the right. The more you adjust the rings (as noted they may be glued down) the more something else will potentially need adjustment.

My CRT is a replacement purchased off eBay.
