Unusually among recent Shindos, the Cortons' output transformers can be wired for 4-ohm output, which I duly did."

Matt, what does the last phrase in black mean ?
I think it's basically setting the output taps (binding posts) on the amp to be optimal for four ohm speaker loads..this involves rewiring the transformers. Some amps already come with 4, 8 or 16 ohm taps.
