Projects

Here are some recent projects I have built. I really enjoy building equipment - not just amplifiers and streaming players but also test equipment. Some are a work in progress. Note the "JWT" vanity stickers on some of the devices I had printed up. On some of the test equipment, I have made custom front panels. As I build more stuff, it will get added here.

Digital streamer based on a Raspberry Pi (2018)
Another Pi-based streamer (2021)
Class A power amp inspired by Nelson Pass's First Watt F7
Distortion analyzer using an old EMU 0404
Passive preamp with stepped attenuator and analog crossover
Class A-B power amp based on a design by DIY Audio contributor XRK971
LXmini 2-way loudspeakers designed by Siegfried Linkwitz (WIP)
New/Old workbench setup
Low distortion oscillator and notch filter
Balanced Stepped Attenuator
Dummy load for amp testing
An Alternative to Raspberry Pi for LMS
And probably more to come......
