The electron vacuum tube is a marvelous device. It makes possible the performing of operations with precision and amazing in conception, like in the vacuum tube amps for guitar and audio. This web site is the most practical way to introduce a number of guitar tube amp and audio tube amp projects for those who not only like tube amps as "musical instruments", but listen and play music as well. My relationship with tube amp design and construction spans more than two decades . I hope all hand-crafted amps presented here will give you years of enjoyment, and highly musical results.
