mosfet audio quality

I have extensive experience with audio mosfets including a design that was capable of 0.0008% THD @ 1 kHz @ 350W (almost the limit of AP test equipment). The unit's final THD was actually limited by some op-amp stages, although more modern op-amps would fix that.

The IR circuit is in comparison complete rubbish and very basic, although it teaches the basic fundamentals.

Isn't the LM3886 one of National's 'Overture' ? series used in the 'gainclone' type kits ? It's very well regarded. I know someone who just built one and has nothing but praise for it.

Ouch.

Sounds good. I read bits and pieces of Slone's book online (books.google), and requested a similar book from the library (it should be arriving soon, from a different library branch).

Thanks,

Well it's little worse that Hitachi's early app notes ! Except that Hitachi gave vastly more support info.

Google 'gainclone' but ignore all the audiophool voodoo s*it. Concentrate on the engineering aspects of it, They're basically decent IC amplifiers.

The Nat Semi data is free online of course.
