So, I am building a Neve 1073 pre/eq clone including its PSU. For the PSU I received (as part of the diy body kit) a toroidal transformer, without a brand name, type number or any data sheet. The only info given is pri: 115v white, 115v black. Sek: 18v red 18 blue, 50VA. So I’m quite confused on which leads are live and which ones are neutral. I will post some pics down here.

Could anyone please help me to identify the live and neutral wires? Or is this of no importance because all are relative until you connect one of them to neutral on the pcb/power plug?
