But you need to go here and watch this video. MOST (if not all) of the cheap
hard to find parts on EBay from the far east are counterfeit.

Is it me, or is it normal practice to switch an electronic product off
before changing the transistor?

He compains it gets hot and wonders why. Would it be that the metal
bit on that TO-220 transistor needs to be connected to a device called
a heat sink?

I'm not saying they are not fake parts, but he sure has a funny way of
testing them.
