...or just one, if you can find a "universal" 120/240 volt transformer of sufficient VA rating (the secondary is NC, so the secondary voltage doesn't matter).    I'm not as artistic, so I'll borrow the artwork and just add a couple of lines.  The "split bobbin" types are fairly common, even in 220 vac countries, as it lets a manufacturer change the nameplate voltage of a linear power supply with just a change of jumper and fuse.
