The Elektor article index has moved to its own page here .

This is a so far incomplete (but growing) collection of the significant EW audio articles. If nothing is shown for a given year, without further explanation, this simply means I haven't got round to it yet.
The article titles have been altered where necessary so they give some clue as to what it is about.
I have given some of them my own rating as to worthiness; if you disagree please let me know. In a few cases I have put down my thoughts on their value... click on "Comments".
Most of my articles up to 2004 are now available in one handy volume: Self on Audio The perfect gift for all the family.
Some of the older articles which are out of copyright are available in the Wireless World Archive section of the Amplifier Institute. Where this is the case clickin on "Article" to the right will take you straight there. Any comments I have will be found with the article.

First-rate.
Innovative One of mine.
As good as I can make it. Competent
but unexciting Misleading or
pointless Just plain wrong!
Sorry but there it is.
Repeat offenders have colours assigned to their names.

The first issue titled "Electronics & Wireless World" came out in October 1983.
Before that, "For Everything In Electronics" had appeared above "Wireless World",
for the April 1983 to September 1983 issues. Clearly there was concern about the outdated name. However, up to April 1984 only "Wireless World" appeared on the spine.

Curiously the Nov 1986 issue had a completely blank spine. Presumably a printing error.
