[quote author="chrissugar"]Ok, now I'm scared because last week I bought 200 TOSHIBA 2N3055 transistors [ for enough NEVE pres for the next 100 years] and the price was too good. I was suspicious and verified the aspect and the logo and seemed ok but now I think I will have to make some serious tests.

Well I guess you can open one up and compare it with the "good" 3055 in the photo at the bottom of that page.
In the Canada section, there's a bit on a fake Motorola 3055.
