Easy, get a (build) a power supply that uses a transformer with dual
primary windings (2 x 115VAC) and a suitable mains selector switch which
simply puts the windings in parallel or series. This is how it used to be
done in the old days and being linear is

Subject: 1 230/115V

Is there a reasonable way to have a 6u suitcase frame work with both 230 and
115 volts IE, I want to be able to play it in Europe and the States.

From checking the previous discussions, I understand that a switching power
supply has been tested and proven problematic. But is there an actual
solution Could two separate power supply units be installed in the
suitcase, for example Or an external power supply One installed for 230V
and another external

I am based in Europe, so most of the time I'll need 230V.
Step up transformers tend to be not very portable...
