I took a pic of the inside one of these, but noticed some thing a little different from the pics DannO posted.
Mine are missing 2 caps next to the left transformer and that the transformer is a diff. colour... thats the most obvious one I see

They use metal rails that are mounted externally, instead of using a thicker 4 layer board and putting copper traces within the layers of the board. When copper trace is used the board is usually green(as far as I have noticed, Now some rail amps also do have a green board so maybe my theory is wrong but.....)

Yup, you're theories are wrong.
Color of the board has nothing to do with anything, that's just the choice in solder mask. You can get them red... blue... green... hell even black if you want but some companies charge more for different colors depending how common it is, so their choice in color of board could simply be the cheapest avaliable from their board company.
And mounting thick metal rails or using cables to transfer large amounts of current is a damn good thing, you can transfer alot more power through them opposed to copper area's on a layer within a board layout plus they can dicipate heat easier if you're dealing with huge power, copper layers inside the board can't. The only way you could get large power transfer using the copper within the board is to buy high oz copper boards... they can get pretty pricey for the good ones. So why spend the extra when you buy cheap boards and transfer your power with cheap rails or wires?
ya man that amp is totaly different from the us amp the caps are freaking huge and is filled through out the amp . This would crush the layout on the us amp with very small chips on the board. I would love to test this amp out but i dont got the funds so Less get us some scores yo
nice buy
