It's not a switcher. As is common for linear power supplies (and not
uncommon for switchers), there's an input voltage selector as part of
the input power connector/fuse/switch combo.
Since the power transformer is 15 of the 22 pounds weight, one of my
thoughts was to ship that part (or an extra) ahead when traveling, and
when I asked was told that currently it takes about 15 minutes to
install, but that time might be cut.

Any switching supply today and one that's "worth it's salt" should operate
satisfactorily from 100 VAC to 250 VAC. So 120 VAC or 230VAC should not be
of conern.
