The IC package looks identical to the TDA2050s I just bought from digikey last week including the tab. The fake ones I bought off ebay had the side scoops higher and other differences. Also, the pins were thin near the epoxy.

With the same supply, the fakes put out about three watts less before clipping and the die size was 1/3rd when I opened them up!
