I?m building a 2 channel green pre as my first project and I have the boards stuffed. Thanks to all the question askers and answerers who's previous posts have meant I haven't had to ask any questions of my own up to this point. :thumb:
I think I have everything else I need to wire it up and I have a few questions with this bit.
First- wiring the power transformer. I have an idea what I?m doing with this having read previous threads but most of the stuff I?ve read has been for US mains voltage (primaries in parallell) and I?m in the UK. Here?s the wiring diagram for the toroidal transformer I have:
Having looked at the diagram here:

I think I need to hook it up as follows:
Primaries
Grey- Live
Violet- neutral
Blue and brown- do these get connected together and then not connect to anything else?
Secondaries
Red- 15v on the psu pcb
Orange- other 15v on psu pcb
Black and yellow- 0v on psu pcb
So how right/wrong have I got this? :green:
A few other hopefully straightforward questions- what amp rating should the fuse be?
For the on/off switch I have what I believe to be a DPST switch with four poles on the back. How do I hook this up?
Thanks for any help you can offer folks
Cheers
Nick
