Abstract: This paper describes the complete design of the hybrid vacuum tube amplifier for home using. The described amplifier has 3 digital inputs (TOSLINK, Sony/Philips Digital InterFace and AES3), a single analog input and a single input for the measuring microphone (for the calibration of the entire system). The paper further discuss the design of a preamplifier for analog inputs, the receiver of digital inputs, DSP circuits, power and head phones amplifier and the power source. The complex audio system is controlled by an 8-bit microprocessor and has a graphics output implemented through an OLED display. The goal of this paper is to design and build a high quality amplifier.
