I am in possession of a transformer 240> 110V equipment for the Japanese returned to As the years is a light table, Japanese consoles, Japanese arcade, dvd player, mini chain, md, ipod player 2004. The first that I bought 20 years ago was a small 75watt, I quickly invested in a bigger 300w for more intensive systems (screens, consoles recent) then that last bit to dedicate it to use in my living room. Like the larger model HQ there is no noise. Level size is perfect, he 9x9x12cm.
