    All the bits arrived in double quick time. Now I need some help confirming the wiring colours and general connections.

    Here is the toroid: 750VA 2x24 from airlink

    Here is a circuit I've drawn up but need help with:
    1. Toroid blue and brown I assume are mains input?
    2. 4 output wires are from the pair of windings? - but which to connect to the regulator and in which order?
    3. I'll mount all this on an aluminium plate which will go to earth - does the centre GND output on the DC side need to be earthed as well?

    I'm away from the parts at the moment otherwise I would at least give you the resistance readings across the toroid wires, but hopefully the above is enough.

    Thanks
