Welcome to Atrad-Audio. This site is all about valve (tube) amplifiers for hifi.

This is not a commercial site, though I can make you an amplifier if you get in touch. Some examples of the previous amps I’ve built are in the gallery. Some are one-off builds, others can be requested. Or, a brand new build can be designed. See the Getting Started page for more info.

Why vacuum tube / valve amplifiers? Even though tubes were superseded by modern electronics long ago, audio enthusiasts never stopped loving their warm, smooth and engaging sound – whether listening to vinyl, or modern digital sources, and regardless of music style. Many feel that the vacuum tube sound just adds another dimension to the music.

Why we do this

As well as their sound, they also look awesome. Because what’s not to love about a glass bottle with red-hot insides and a high-voltage blue glow? A real steampunk vibe.
