What a hideous hack!

A very FAMOUS hack that produced the first truly new audio power amplifier concept
in decades.

A complementary-pair class B amp, with a b-e resistor to somewhat
smooth the gap in the transfer function, has been in use since at
least the mid-60's. Only audiophools whould consider this to be a
great concept, much less a famous invention.

It's still bloated, hideous, and obviously designed by fiddling. D5
and D6 must have been added to increase the already bad TIM
distortion.

Audio is such crap.
