New Linear Audio publication!

Just received my copy of Volume 6. Thanks to all the contributors.

So far, I have read Daniel M. Joffe's article " Practical Electronic Control of Class AB Output Stage Quiescent Current". I picked this article first because it parallels some information I am focused on in Bob Cordell's book.

Though most of the details are above my head, I picked up some good information. I am sure I will have to read this article several times to digest more information.

Now to figure out what to do with the Linear System JFET's.
 
Linear Audio Volume 7 published!

Sorry guys, took me a bit longer, but here it is: Linear Audio Volume 7!
No less than four new authors joining the incredible crew I already had. Finally was able to convince both Barrie Gilbert and Malcolm Hawksford to share some of their experience and knowledge.

We start of with a guest editorial by Joachim Gerhard who documents, from a personal view, his year-long adventure through listening space to end up with the G-pole speaker.

Barrie Gilbert contributes the 1st part of several, starting with explaining how to use simulation for design in an intelligent way. Malcolm Hawksford draws on many years of teaching to give us an overview of equalization in audio.

Giovanni Stochino, who should not need any introduction for Wireless World / Electronics World readers, reviews the results of many years of research covering different error correction topologies and discussing their pro's and con's.

Several circuit design articles discuss advanced power amplifiers (David Zan), a simple yet effective low noise measurement amplifier (Burkhard Vogel), and a hybrid phono preamp (Stuart Yaniger).

George Ntanavaras went on a quest for the ideal speaker enclosure shape for surround use and came up with the Prisma loudspeaker.

Vol 7 has two reviews: Marcel van de Gevel read Morgan Jones's 2nd edition of Building Valve Amplifiers, and Stuart Yaniger and yours truly reviewed the Smyth Research Realiser A8, a 'listening room / speaker virtualiser'.

And, traditionally, Stan Curtis in his column throws down a gauntlet with a possible way to explain (and cure) audible differences between different implementations of the same circuit. If you have an idea on how to verify his solution in a controlled way, let me know!

As usual, all abstracts and author bios are on linearaudio.net.
Happy reading, but don’t forget to listen to your music!
