Obsessive hand-crafted stereo tube amplifiers.

Amplifiers are made to order and typically take 1-2 weeks. I hand-craft each one myself in Malvern, PA and put every amplifier through measurement tests and listening tests before shipping. Read more details about each one and feel free to send an e-mail if you have any questions, or read my online FAQ. Some of these are also available as a DIY kit for full hands-on builders.
