From the looks of them thye are the Russain Cyctahoh's. These were kick ass about 3 years ago. Then the fakes started....man oh man this sucked! from the looks of it you got fakes, the labels are CLOSE -- but this particular
amp had some seriously good fakes out there that were hard to tell. I even got duped once.
Then they came out with them saying in red: "For Sale in Lithuania Only" written across the label -- these were good, and if you get some now, they are legit and have not been faked yet. For NOW: ONLY TRUST THE ONES THAT HAVE "SUST 250" STAMPED ON THE LABEL WRITTEN IN GREEN --- which goes across the label horizonatally. While there is a chance you have an old batch I think it is highly unlikely due to the high number of fakes this item had. Hope I helped.
