    If you ever drop into Rocky Doc I'll take you to a fish-n-chip shop that sells a most truly awesome battered Barra.

    Fine job on the power lead.... Brown wire to the Left pin (when viewed from the cord side of the plug) as us Aussies Always keep Left... Same goes for the wall socket as you look at it ready to plug your appliance in, Earth is the bottom hole, Active is the Left hole and Neutral is the Right hole.

    A clean up tip for your soldering. A cotton bud soaked in Acetone will remove/dissolve most if not all of the burnt/used flux. Use with caution as the highly flammable Acetone will also melt some plastic stems that some cotton buds use, it will remove all oil from your skin and some labels off components, but it will not harm the solder joint or the fibreglass PCB.

    That battered barra sounds nice so I'll definitely keep that in mind, barra is always good eating, the convention with Australia's 240 V AC wiring goes like this, the brown wire is Active, the blue wire is Neutral, and the Green/Yellow wire is the Earth wire, and it is standard practice to put the 240 V AC mains fuse in line with the Active wire but after the power switch, reason for this is that if for some reason a short-circuit develops in the mains transformer, the fuse will blow and cut the power off preventing the chassis from becoming live, and the Earth wire is always securely connected to the chassis too as an extra safety measure.
