The website of Stephie Bench

This information was placed here with the kind permission of Stephie Bench, a most interesting and friendly person, that I met at the 2004 European Triode Festival in Langenargen, Germany.

Her website is a collection of some of the most interesting and amazing tube design ideas I have ever seen, but it got removed by AOL from the internet, as they shut down their homepage services. I had the idea to place a mirror here at the jacmusic website, and her immediate response was positive. The things you'll read about are not just ideas, these are working designs, and I want to document those here, and keep it alive. This information is put together by somebody who went to the bottom of things, with 30 years of design experience and tube passion. She has 10 patents on her name, so this is not just somebody. Then put several years of hard work in following and realizing some really very unusual tube design concepts, and stay down to earth during all that time. I think very few people are like this.

Last time we met, at the European Triode Festival, there was a blind hearing contest for tube RIAA Phono pre-amplifiers. Let me tell you more about this. A tube phono amp is a very difficult amplifier. There were several great names presenting their creations there, like Jean Hiraga, Linn Olson and Steve Bench. Also some very talented DIY who build phono pre-amps of finest quality as well.

So we could not see which pre-amp was playing, and also you could not see the pre-amps. So there was only the sound of it, and the same song was repeated. The winning product was a battery operated pre-amp, hand-wired into a tiny little box, with pencil tubes. I remember I also voted for this one. And guess who build it.... Congratulations Stephie!


I do not just want to place a mirror of this website here, without a short note about the author. Stephie had her gender changed to female, so you will see the name Steve in the original texts. The picture is a recent one.

This information in the following link is copy righted. It is a package full of information, craziest ideas, and amazingly interesting tube circuits that are all tested, and investigations of tube circuits, schematics and research on tube curves. This represents a decade of work by not just somebody, but by a top class electronics expert, industry consultant, and multiple patent owner, who tries to understand and prove why things work as they do. Check about "sound of capacitors", or about how to use a tube grid as anode, and the anode as grid. Better check everything. This is a mixture of classical approach with unexpected methods to design circuits and test them. And hey.... these circuits all WORK. Stephie represents this in such an understandable and inspiring way! Thanks to Stephie Bench, for personally giving me the friendly permission to add the full information to the JACMUSIC website.
