This past winter, I discovered a community of people online who build their own audio equipment based on old vacuum tube and transformer technology. I’m an engineer by trade (BioEng/ChemEng) and couldn’t help myself so I learned all about audio circuits, ordered a bunch of components, and got to work with the soldering iron to build this SE amplifier. It needed a chassis, so I built this box from red oak and cherry with an aluminum top. It is constructed with mitered ends, supported by corner keys and splines – alternating the contrasting wood for aesthetics – and the polished aluminum top rests in a rabbeted groove. There is quite a bit of hidden support because the transformers (blue things) are mostly steel and very heavy. It was a really fun project and I love how it turned out. And it sounds great. This photo was taken before the wood was finished with a simple clear coat; at some point I’ll add the final photo of it operating in the entertainment center that I previously posted.
