Eduard Broekman Diy-Fi
This is my personal channel. I design and build tube-amplifiers, speakers and soon, dacs. My aim is musical reproduction which works well for both acoustic performances such as live jazz bands as well as the omni-present and effortless quality of high quality PA systems. In my vlog videos I share my first hand experiences in trying to reach this goal.
