The Fake Chip Scourge
New video from Asianometry
Not sure scavenging e-waste is a bad thing. Esp. for vintage audio chips. If not too much blow torch heat or violence is used in extracting them from discarded equip, chances are the chips are still in good nick.

I used to rescue old chips and passive components from computer PCB putting them directly over the kitchen gas burner. The majority supported the procces.
I got a bunch of recycled counterfeit chips once; they'd been remarked as a (mostly) functionally identical but more valuable type. A significant number of them were defective, however, which was a big red flag. None of the hundreds of genuine chips I'd previously used had ever been DOA.
More recently, the power MOSFETs in a cheap solar charge controller look recycled; like they've been hauled halfway across China by tuk-tuk in a bucket. The charge controller works fine, though.

Rather than use fake chips I have been chip hopping.
I went from PIC16F175 to PIC16F1613, PIC16f1718 to PIC16f1788.
Means making slight changes to code but generally compatible.
I have bought cheap components off ebay and had problems so I try to stay away from ebay/China if possible.
