The price has been drastically reduced! 2024/3/8 sales price 448,000 yen This is a 2-amp amplifier that Uesugi Laboratory founder Yoshiro Uesugi joined his soul. In addition to eliminating feedback (negative feedback) from overalls and preventing the speaker driving signal from returning to the initial stage, it is a power amplifier that achieves high speaker driving power by reducing the impedance of the amplification stage and proper feedback (negative feedback) for each stage. There are scratches on the exterior. Serial 2310015/2310016 (Tamura Eiji)
