A "240" V. to "120" V. autotransformer of an appropriate VA rating takes care of the voltage requirement.  Many units, regardless of technology, have power transformers suitable for use at either 50 or 60 Hz.  A unit with a trafo rated only for 60 Hz. might overheat.

BTW, many devices come with power trafos that have dual primaries.  The primaries are connected in parallel for "120" V. and in series for "240" V.

[quote author=Rojoh  link=1154053264/0#2 date=1156436956]Hello! I'm a norwegian audiphile, and I found the ZSLA-1 very interesting. The problem is the mains voltage. Do any of you know if the transformer could be wired to 240V, or do I have to use a voltage-transformer? (Or perhaps it's possible to replace the original transformer with a 240V version?)

Johan,

Send Steve D. an EMail or use the private message capability of this board.  Many DECWARE models are available for use in "240" V. countries.  Steve will tell you exactly what you need to know.
