first -- Self isn't a fan of MOSFET's, Randy is a proponent.

secondly -- if you have analog design skills the folks at TI, Nat Semi,
Linear Tech, ADI and Maxim would like to talk with you.

third -- Slone is out front with his "life ethic", and a lot of
"red-state-o-phobes" don't like it.

Twaddle, stuff, and nonsense


Basically this whole book is the effort of a hayseed electronics vendor
to peddle his own kits of plain vanilla grade stereo equipment. With
skilled electronic assemblers in America getting $8.30/hr (and equally
skilled Asians getting that per day!) and components in hobby
quantities bringing a 50 to 500 percent premium over what commercial
buyers pay even in 100 piece quantities, he claims a hobbyist can
better commercial grade designs in his hobby workshop cheaper.

This reminds me of Fred Willard's character in the excellent film, "A
Mighty Wind". One of his catchphrases-"I Don't Think So!"-applies here.


These amp designs, apparently mostly from Douglas Self's books, are
nothing special or unique: as someone else pointed out, if they were,
there would be dozens of amplifiers of "Slone type" sold ,just as many
companies made "Williamson style" amplifiers, without compensating DTN
Williamson, during the early postwar hi-fi era.

About the only justification for homebrewing audio amps is to get a
design offered commercially only as a "high end" piece at huge expense
(and gross margin) or not at all. You can get an education, perhaps,
but a breadboard project of a couple watts can give you that, and
besides, audio amp design isn't exactly in big demand: the websites of
High End, pro, and mainstream audio equipment manufacturers list
continuing job vacancies for DSP software engineers but never analog
designers.
