Stop press (or rather, don't ....)
After
a lot of head-scratching and even more lost sleep, I am launching a new
printed audio publication for anyone who is
interested in technical audio articles, solid state, tube, amplifiers,
loudspeakers, digital, what have you.
The premier issue, Linear Audio Volume 0, has articles by audio giants like Nelson Pass, Siegfried Linkwitz, Douglas Self, Bob Cordell, Tom Nousaine and many others.
The content, article abstracts and author bios can be read here.
You can already order it if you want, I start to ship 30 August. Check it out, let me know what you think!
My interview with Dr. Lohstroh who designed and build what became known as 'the Otala amp' for MultiMediaManufacturer. Lohstroh is nowadays more into making and arranging music rather than listening to it, and there's a short video here.
I recently found out that in 1997, John Atkinson of Stereophile referenced an article of me in Audio Amateur "Negative feedback - curse or blessing". I seem to support no one less than Martin Colloms! ;-)
I'm reading "The crucible of consciousness - an integrated theory of mind and brain" by Zoltan Torey. Just after the first few pages something clicked in my brain...
Jean Hiraga's minimal amplifier: just one (1!) MOSFET: the Nemesis. I finished rebuilding this classic, BUT I still am not happy with the power supply. Am now putting togeether a VICOR smps with RAM (Ripple Attenuator Module). Stay tuned!
New in My Library: TI's Ron Mancini has put together a nice guide to amplifier stability. Recommended!
All other T-reg stuff moved here.
Stop press! There is an error on the DN2540 plug-in board available through Elektor. One end of R3 is going nowhere - this should be connected to K2. My apologies, it is entirely my fault. Thanks John Lopez!
As noted, the T-reg is based on the MC1466L floating voltage/current reg chip, now obsolete. Interestingly, Gary Lecomte has developed a discrete version (pcb actually) of that MC1466L! (Thanks John O'Neill).
I started a page of favorite quotes and other useless facts. If you want to contribute, mail me!
Enjoy!

Welcome to my place!
It’s great to have you here. Take a look around
by clicking the links on the left. Stay as long as you
like. By all means, ask if you don’t see what you need,
or better yet, give me your opinion!
Talk to me!

what am I reading?
Books or articles that I find
interesting but have no bearing on audio (at least not
directly...)
What’s in a name is where I tell you who am I and what’s my drive when I design audio.
Been there, done that - I’ve done some designs and wrote some articles in the past which have been published.
Musings is a page where I muse about things that
strike me and may or may not be relevant to audio.
My Library will lead to a list of articles that are classics and, in my opinion at least, significant to further our understanding of audio technology. They are meant for personal study only.
Good Stuff are links, documents and places of audio interest. It will change over time so come back once in a while.
