Some years ago I designed and built my first hi-fi vacuum tube amplifier. The entire process took almost one year, designing, simulating, and prototyping, before actually building the amplifier.
After the first one, the second came, the third, and so on… I become somehow addicted 🙂 . Recently, I also built a pair of speakers.
In this web site you will find some information on my works.
You will also find my guide to Hi-Fi vacuum tube amplifier design. Hope you might appreciate it.
