Product Background
This product references the circuit design of the classic JC-2 pre-amplifier, utilizing a fully symmetrical Field Effect Transistor (FET) pure Class A input architecture. It stably achieves Class A output ranging from 20mA to 25mA. The core components are Toshiba K170BL/J74BL, a classic paired FET. The entire unit is crafted with high-end, audiophile-grade components, faithfully reproducing the transparent, pure, and high-resolution sound characteristics of classic amplifiers, and embodying the elegant sound quality and charm of a hall-of-fame pre-amplifier.
