Before disposing an otherwise unusable board, I'm used to recycle components that are easy to remove. I used such components successfully in experiments in the past. But I wonder if they are reliable.
In this case I recovered them from a boar with at least three electrolytic capacitors leaked. I measured these from the picture with a tester and they are all around 9µF (marked as 10µF) so I guess they are within 15% tolerance, and that should be ok.
But is there a chance that they are further damaged?
Transistors over there have all 190 hFE according to the tester. If I can confirm that with the datasheet, should I trust them?
What about LM78XX?
I would like to know your general opinion about components recycling.
