I've been too busy lately, working on the book, to look at the conversations around recent x-Chapter draft postings, but will get time soon. Meanwhile, an email from our editor prompted a post this morning:
Power Transistors for Linear Amplifiers, 3x.18, will be elevated back to its proper position as a full-blown section of its own, now keyed as \xahead, and not merely \ahead.
The DRAFT is pre-fix. Check out Table 3x.6, and study the graphs in Figures 3.117 and 3x.118, what an interesting set of curves! I gathered candidate parts, Paul took SMU measurements, polished graphs in Illustrator.
I look forward to seeing suggestions and comments from the DIY audiophile crowd.
