You will need a step-down transformer.
Always use one rated for at least twice the rating of the load that will be connected to it.
In your case, that means not less than 2 A, or 240 watts.
250 watt transformers should be readily available.
Also, note that the amplifier is rated for 60 Hz power.
Operating it on 50 Hz may cause problems with hum,
and its internal power transformer, if it has one, may overheat.
Altogether, you would be better off buying equipment
that was Made to be used Where it will be used.
