Tube amplifiers

I like to design, build and listen to vacuum tube amplifiers. I don't want to debate whether the sound from a tube amp is better than from a solid state or not, I think the sound is very good from my tube amps so I use them when I listen to music.
The main reason I am working with this old technology is just that, I am fascinated that you so easily can get so good sound from technology that is nearly 100 years old. As my day to day work is with the very latest technology, (I work with mobile telephone systems) I think it puts things into an interesting perspective that audio amplifier technology hasn't really improved that much in 100 years.

These pages contain information about my amplifiers and other information about tubes and tube related technology.
