[Event Day Only] OA-JC5 Vacuum Tube Headphone Amplifier

A vacuum tube amplifier that evokes emotion with realistic midrange expression
The OA-JC5 is a hybrid headphone amplifier with a traditional 12AU7 vacuum tube in the pre-stage and 2SA1943 and 2SC5200 transistors in the post-stage.

◆It provides rich, clear sound quality that combines the warmth unique to vacuum tubes with the precision of transistors. The soft glow of the filaments and the blue light of the LEDs deepen and enrich the music listening experience.
◆By using different circuit configurations for the front and rear stages, precise, noise-free signal amplification is achieved, realizing a rich and expansive sound that fully encompasses all the sound components of the music.

Specifications

*For the JOYCRAFT series, Oriolus has completed the audio circuit, and it is an assembly product where customers themselves attach the vacuum tubes to the sockets and assemble the frame.
*The unit requires a separately sold AC adapter (DC20V) to operate. (PD-compatible AC adapter and USB-C cable are not included).
*(Regarding warranty) Due to the nature of a DIY kit, the warranty is basically only for initial defects. Failures and damages caused by replacement or modification of vacuum tube parts are not covered.
