How easy thst is depends on the design of the
input stage of the PSU.
PSUs that are designed to run at either mains votlage with simple-ish
conversions run the chopper circuti from 350V or so. For 110V mains,
that's got by votlage-doubling the mains, for 230V mains by simply
full-wave (bridge) rectifying it. In amny cases, 4 diodes are fitted all
the time, it's just a matter of cuttign a link to convert from 115V input
to 230V input.
This one seems to be a voltage doubler...
* AC enters via two wires soldered to the PCB
* AC enters a potted black Elmaco 511473-1K (AC line filter?). This has
L/N/E in and L/N out.
