More specifically Rob, the Bridge Rectifier you need to change is BR2 and while you have the board out you should change the associated C5 filter capacitor.
The PCB is printed on both sides so make sure you get a good solder flow on both sides (solder from both sides if you can) check your handy work with a multimeter to ensure a good join (both sides) and you wont have to worry about the jumpers a lot of guys recommend.

Thanks mate will give it a go in a few weeks as I'm banned from repairs until all my Open for Inspection days are done. The boss is non negotiable at the moment until the house is sold.
