Main transformer 2x115 wiring

[poomka]

Hello,

I've almost finished my GSSL, I just need to wire the following main transformer, because it's a 2x115V primary I'm a little confused about how I have to wire it...

Could someone please tell me how I should connect the differents color cables to the IEC socket ? and confirm the connections to the PCB ? I've seen GSSSL with an external transformer connected to the left top of the PCB and some others to the middle left, does it makes any differences ?

Thanks, I could not wait to power this first DIY project and see if it works (It would be kind of magical for me...)

Hello, I don't know your country voltage for mains...

For 120V primary :
- connect gray + maroon to IEC lead
- connect blue + purple to IEC neutral

For 240V primary :
- connect gray to IEC lead
- connect blue + maroon together
- connect purple to IEC neutral

For secondary :
- connect black + yellow to the center of PCB power connection
- connect red to one end of PCB power connection
- connect orange to the other end of PCB power connection

..but please remember, that the colouring of the transformer wires are NOT standard - every type has it's own colour coding!!!!!

Assuming the transformer is radiospares reference number 2574913
(as I found from the transformer link)
