Technics SU-A700 (49,800yen(around the 1994 time)


Country: Japan

Technics adopted power MOS-FET developed uniquely, and has realized the MOS class AA.
A high-quality sound X-Pro power source capacitor is adopted.
A high robustness is secured by the input/output switching of the termination hardwired connection by gilding contact relay.
