This article is somewhat political but is about as political as I want any content on this website to be though the particular issue to be discussed I think is worth bringing up.

In the February issue of Silicon Chip a number of readers wrote to vote against the magazine's attempt to gauge interest in a valve-based stereo amplifier project. As I would like to build a quality stereo amplifier for my computer speakers I have to say that I support the affirmative case for the project's development. To me at least, nothing would sooth the soul better than the glow of rows of KT88 (or similar) power valves behind my laptop. I am sure that there are other people who would like to try this out or use a valve based amplifier on a tape deck, iPod or other similar modern music source.

One reader wrote:

Can we please try to drag Silicon Chip out of the 1950's, full of old fogey's memories of Vintage Radio and the dawn of television?



The reader should do a little more to research their facts. The vintage radio fraternity, whilst centralised in Victoria (that is where all the good stuff can be found), comprises of a great number of younger people who are prepared to spend large chunks of their pay on preserving what are colloquially known as dust collectors but at the end of the day, and I am sure that most who read this will agree, the collection and subsequent preservation of old radios is probably the best way to go about keeping a record of Australia's manufacturing and broadcasting history.

Think of the preservation organisations out there who preserve and operate trains, trams, bullock dreys, motor cars, even blacksmithing - all do a fantastic job at their chosen hobby and once again, all of these groups of people have the young generation supporting the cause. Vintage radio is no different. I'm only 35 and I've been collecting old radios for seventeen years. My first purchase was the chassis of a 1960's Kelvinator mantel set for which I paid $3.00. Things have come a long way since then.

Free speech is one of the greatest aspects of Australia's social fabric. Accordingly I thank Silicon Chip for publishing the letter in question but at the same time I would like to give the magazine every encouragement to begin development of the valve amplifier project and I hope that the magazine continues to be a leading supporter of both the regular Vintage Radio column (Rodney Champness does a great job with this) and a continuing supporter of one-off articles like the recent historical feature about Australia's foray into television broadcasting.

It's all well and good to believe that a magazine like Silicon Chip dedicate their time to projects and articles of a cutting-edge nature, featuring only the latest technological components and functionality but with Silicon Chip as the sole survivor in the electronics monthly game, some may even believe that they have a community responsibility to have a broad base and this is something I think the magazine is doing very well.

I am only 43. I am now a grandfather. I grew up with a radiogram in my bedroom during my youth. I built my first crystal set in 1978. I completed my Radio Trade Apprenticeship in 1983. Even in my short lifetime I have seen the rapid development of elect

There is certainly something about the sound of valve (tube in US parlance) audio amplification that gives it a certian "edge" over solid state equipment. I find this to be more perceivable with power amplifiers then pre-amplifiers - but I do find a well

Above (long) post was written by "seecol" however it would appear that while typing I became logged out.

It is a bug in the software. It is fixed for the next version of the site which is due to go live in the next few weeks. In the meantime I will fix things up. Smile
