Six Transistors and the Truth?
After two more days of thought and a little advice from a nice fellow at diyaudio, I propose a few changes to the "final" circuit. My latest version looks like this:
(Note that the changed part number on Q3 is just a typo fix, the previously listed part was the PNP complement to the correct one.)
Distortion is now below 0.1% at 5W. For thermal purposes, Q2 could actually be two C4883s in parallel, sharing the current.
I'm planning on making a PCB and box for this circuit. I'll post pictures when I'm done.
