Hello good people of GroupDIY. I picked up a Neve 88RS that had been in Korea. I want to wire the psu's for 120v as I'm in the states. There's a board in each PSU that has hookup posts for each of the primary wires of the trafo, presumably so one can wire to work with any mains voltages. There are pairs of posts each with the following values 5, 0, 100, 110, 120.
I'm guessing primary windings can be put in series to get 200, 220, or 240v, or one half can be used to get 100, 110, 120v. If this line of thinking is right, then I think it's currently setup for 220v. Does this sound right? Thoughts

You need to parallel the primaries for the lower voltage, and make sure you get them the right way round.
Thanks for the input @radardoug. So I would take that to mean that I'll tie the 120V posts together and connect the mains hot wire (brown) to those. Then tie the 0V posts together and connect those to mains neutral (blue). Not sure if that's what you meant by the right way around?
