Aurorasound PADA-300B Mono Block Amplifiers

Shinobu Karaki-san's latest masterpiece - the PADA-300B hybrid, push-pull, mono block amplifiers utilizing WE300B valves with an output of 28 Watts per channel.  Design PhilosophyConventional hybrid power amplifiers are constructed using  vacuum tubes in the front-end and transistors for the output stage, the transistors doing the power amplification with the tubes just adding a flavor of the classic tube sound. However, the PADA-300B is designed in the opposite way – the transistors in the front-end and the tubes for the output. The PADA-300B design leverages the transistors to achieve low distortion, high SNR and wide frequency range, and then utilizes  an inter-stage transformer to drive the output tubes. The inter-stage transformer matches the signal level and supplies the voltage difference between the transistors and tubes. This construction makes optimum use of both the advantages of transistor performance as well as the warm tube sound. Noise Prevention and ControlThanks to the
