    If the schematic that you have shown has come with the transformer then follow it.

    on the sec. side short yel and black together then red and orange go to the AC side of the rectifier.

    on the primary side short grey and violet together and connect the mains to brown and blue.

    Before you connect the caps up measure the voltage on the secondary side of the transformer (it should be around 50v AC) With the caps connected DC side it should be about 70v dc (DON'T TOUCH THE CAPS WHEN THEY ARE CHARGED as they will bite you) without a load on they will stay charged for a long time.
    Nice one! The diagram was from the datasheet on rapidonline's website.

    I was using joe's psu as a guide

    On Joe's he's connected the red & orange together, blue and brown are going to the mains, then he only has yellow and black (1 primary core I guess) which he has going at diagonal across the rectifier. I didn't really get what was going on how Joe has it wired but what you said is how I thought it should work ;)

    I'll connect a 10k resistor like Joe across the outputs to discharge the capacitors but will avoid them been bitten more than once repairing ps2's.

    Looking at the rectifier datasheet I can now see why it's connected diagonal

    If you didn't buy it from China the company you bought it from did ;)
