The kind of lab PSU depicted in the video... evokes bad memories!
I had two looking very closely like that. Probably many different chinese manufacturers share the kind of look, like often... anyway.
Now I am known as sensitive to olfactory irritants. But those things were really beyond smelly.
They gave me instant head ache that would only stop when I hauled them in the basement.
There, I let them run on 50% power output (halogen lamps are handy
) for
two weeks non stop, in hopes they'd lose some of the nasty stuff when warm.
Still, they stunk just as bad and still gave me head ache, so I sold those suckers again - recommending it to be used in a well ventilated garage only...
