Do I need a Transformer for YAMAHA HS8

Hey Guys,

I have moved from the UK to the Caribbean, however have all my musical gear back in the UK and I want to know if it is worth shipping out.

My main concern are my Yamaha HS8's.

They are both European ("West European Voltage rates of 220 - 240V by default"). They also run on 50hz.

Where I live, I need to have:

120 Volts and 60hz

Would buying a transformer fix this issue? What wattage transformer would I get?

Thanks
