Quad 44 pre from 115v to 230v

On behalf of a friend of mine, he asked my advice on converting this pre from 115 to 230...
rather than give him the wrong advice could someone enlighten me and him on how this should be soldered up for 230v?

Remove the wire link (left) and the orange link (right), then fit a link where it says 230V with the solid line.

Done.

Top man, I'll pass that on... I actually suggested that but getting a second opinion always helps...
Thank you...
