When I went to the UK a few years ago, I took my Electro 2 and used a basic travel "adapter" to plug straight from the 120V into the 240V, and did switch the internal supply.
If you use a
transformer 230V->115 (that is UK to US voltages) make sure it is enough for the consumption (in Watts) of your instruments. Then you do NOT have to switch the transformer inside the electro (or the fuse) as it should be receiving 115V from the transformer, same as at home.
However if you do not use any in-between tranformers, you should switch the internal electro transformer (from 115 to 230) AND change the fuse to 125mA slo-blow (250v).
You should also carry some
plug adapter so it can be connected to the type of power connector they use in the country you are visiting.
And also make sure that you
put a sticker on your instrument stating what voltage you can connect it to (so when you return home you do mistakenly plug it before setting back the transformer switch AND the change back to the original 250mA (or is it 300mA?) fuse.
If I were you, I would do the internal transformer switching + fuse thing. Less weight to carry around and cheaper too. Good transformers are more expensive than a fuse and can be heavy. Carrying with you a few fuses, might come in handy in case it blows while on tour.
