MiniTron Amplifier

The MiniTron is a high-end vacuum tube stereo amplifier with efficiency, distortion, and power output controlled by a dsPIC30F2023. The innovative system features three main subsystems: a vacuum tube amplifier, a DSP controller, and a high-voltage switching power supply. The fully functional amplifier successfully blends its unique circuitry and specialized processing software to precisely match the radically different worlds of high-voltage analog and low-voltage microcontrollers.
