About the Yamamoto Soundcraft A-08S 45 SET

The Yamamoto Sound Craft A-08S is a highly regarded single-ended triode amplifier designed and manufactured in Japan by Shigeki Yamamoto. It delivers 2 watts of output power per channel using 45 vacuum tubes as the output stage, driven by 717A mini triode driver tubes and an 80 rectifier tube. The amplifier is renowned for its exceptional sound quality despite its modest power output, making it suitable for use with high-efficiency speakers (96 dB minimum recommended). The A-08S comes equipped with NOS (new old stock) vintage American tubes including genuine RCA 45s and Western Electric 717A drivers. The chassis features a cherry wood and composite construction with ebony legs, and all transformers are custom-designed cut-core units with Teflon insulation. The amplifier is known for its extremely low background noise, transparency, tonal accuracy, and ability to reveal fine details in recordings. It is available both as a finished unit and as a kit. The newer A-08SS model represents an evolution with improved component quality, though the original A-08S remains highly sought after by audiophiles.
