We would really appreciate it if you put ur Amps or wadever you are trying to power's Wattage rating...not the sound output...but the electricity consumtion figures...either amps or watts...

a 1 kva step down transformer 240/120 will give you 10 amps approx and is more than enough for the amplifier

You could just switch to a slow-blow fuse, although this may not protect from things like lightning.
