Well... If you got a heap-o and really want to know, then you can do this: Got a microscope? Got a dremmel?
Pop the lid. Crush it in a vise. Whazzevah. Look at the die. Now the tricky part: See if it matches anything you recognize from dissecting other blown chips.
It’s a crap shoot as to what you see. Sometimes the company logo and part number is on the die. Sometimes, there’s just a couple bond wires inside to fool a customer into buying a jumper. Sometimes it’s pure unobtanium idunna. It’s fun to investigate what the other humans were thinking.
Kinda like figuring out what’s in bios or eerom, your car’s non-odb codes, what’s this microcontroller programmed to do, etc.
This is nothing new. I have an RCA 1929 “60” receiver. It has large metal cans with parts inside, filled with goopy wax so you can’t fix them. Actually, though, you can melt them out. I haven't done it yet, but maybe this spring....
God Bless
