In spring of 2010, I rekindled my love for vacuum tube audio. I built a tube hybrid headphone amp based on an open source design and it sounded amazing. By summer, I started designing and prototyping a tube based hi-fi power amp from scratch - No borrowed schematics just classic techniques, math, CAD and trial & error (see 2010 postings). To log my daily progress, lessons, and results, a blog seems to be a natural tool. If you find it interesting - cool! If not, well, go back to Facebook.
