    I ran across this recently. Some people have mentioned having units in the shop repeatedly, with the same problem coming back (blown power amp).

    Maybe this was the problem. Most likely the parts mentioned in the links are not the only ones counterfeited.

    Notice also that some parts were from "reputable" sources, who got egg on their faces from the issue.

    Since there was a problem with "counterfeit" high strength bolts for use on airplanes, I guess they finally made it down to the poor electronic tech when the other markets dried up.

    Luckily most seem to be offshore from the US, but I bet it starts here pretty soon. No purchasing agent can resist cheaper unless it is proved not to be right........

    This is nothing new, really. I used to shy away from "generic" replacement semiconductors, back in the 70s and 80s, but they were always around, and someone was definitely buying and using them.

    Yeah, there's counterfeit "everything". I just found some tubes labelled RCA, that aren't. If you look carefully you can see the "A" in RCA looks a little different. Ten seconds in a tube amp would be enough to tell the difference, these tubes sound lousy, but if you were on eBay and in a hurry, you might not notice the subtle differences. Caveat emptor, as always.
