Yep. Even for things where we do have lots of docs,
i.e. Tektronix
gear, you will see things like such-and-such an IC is a linear
amplifier and the vendor is.... Tektronix. With no alternate
manufacturer part number listed.
Great! So how the hell do we know what to use to replace such a
failed linear amplifier?
This problem is really not a whole lot different from an ASIC. Mystery
black box, basically.
