Sorry to push back on this but I'm a little suspicious. I found a list of (independent) errata for the 2nd edition [0], presumably because it was used in a class. I see one note about the "Rule 2" for transistors but, to me at least, it looks like the author just forgot a "not" in the sentence. In general, the errata looks like what would exist for a textbook that was written by a person. It has mistakes, mostly typos but just a quick glance doesn't uncover some fundamental lack of knowledge from the authors part. I'm no expert in electronics, so I don't have enough confidence to make a statement about the competency of Scherz, but your assessment seems hyperbolic.
