(Plus/128/512k) Centering image on CRT

I have a Plus analogue board here that's producing an image that's too wide. If I adjust the variable inductor to bring the width to about the right place, it is right but the screen is offset to the left. I can't find an offset adjustment on these ABs: what can I adjust, if anything?

Hm, on thinking about this, is this actually an LB issue, that the timing between hsync and the start of the line is off somehow?

You should be able to adjust the centering of the image using the centering rings on the deflection yoke, and there might be vertical and horizontal adjustment on the analog board
