Rosedanny - The 500W and 1000W transformers each have a thin cord. It has nothing to do with the performance, however. Your Luxman is 210W - so it is double, and is therefore more than adaquate. I have the 1000W. A gentleman who bought Luxman 509U new from Japan for $5,000 used a heavy-duty US-made transformer. He was getting a 'hum' because the cords cannot have a third prong/ground-pin. He replaced it with a 1500W Japanese transformer - and there was no longer any 'hum' - dead silent. There are three brands you can use: (1) Nissyo, (2) Kashimura, and, (3) Sanyo. You could have saved more money if you wanted a heavy-duty transformer by ordering one from 'Joynetmall.com'. But you have to pay for the transformer. $2,280 for the Luxman L505U (using pay-pal), and $160 for a Nissyo 1500W transformer (plus shipping costs). That is why I told you to call me. I believe I was the first to order the Luxman L505U from Japan in this manner. I ordered it 20 months ago. None of the Japanese on-line stores will give you the 1500W for free. On the matter concerning the translation of the owner's manual into English, let me look into that.
