Sony MHC-GN88D mini Stereo

[Dakotaray]

I am getting this model is it for USA Voltage? I haven’t seen the Back Pannel or will I have to get a Special Transformer? Was this model released in the USA ever? If I get it would i need to get (2) Transformers 1 for the main unit & 1 for the Sub wooden which is a Powered Sub-Woofer!!
