[c-nsp] 7606 power supply issue

[nealr]

    Where did you find them? There are lots and lots and lots of 
counterfeits in the lower end products - can't trust a bit of WIC/VIC, 
NM, etc that you might find on Ebay. It wouldn't surprise me a bit if 
there were outright copies of power supplies or people relabeling 
smaller output supplies to look like something else.
