Current driven Output-stage class AB power amplifier

An error crept into the final Current Source Driven amplifier, page 143, figure 4. The polarity of the output transistors should be swapped. A corrected figure can be downloaded here. Apologies to readers and to Ian for not spotting this in time.

The finalised charge pull-out mods are now available at http://www.diyaudio.com/forums/solid-state/305943-current-source-driven-power-transistors-mitigating-cross-conduction-distortion-post5081259.html with a download for simulations.
