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

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