Transistor Tear Down and Compare - Counterfeit Parts Exposed!!!
You are watching a teard down and compare of two TO-3 style power transistors (2N3055, 2N3771,2N3772, 2N3885, etc... ). I show how a "real" part differs from a Chinese Knock-off. This is why you should buy electronic components from reputable sources. Having said that, in case you are a glutton for punishment here is a link to my Amazon store: https://www.amazon.com/shop/sevenfort...
