Oriolus OA-JC1(Digital Power Amplifier)JOYCRAFT DIY Series
Classic 12AU7 Vacuum Tube Amplifier Circuit
The OA-JC1 features a precise two-stage amplifier structure. The first stage of the amplifier uses the classic 12AU7 vacuum tube, which has been in use for over 80 years and is known for its rich, smooth sound character. In the amplifier's second stage, it employs Texas Instruments' TPA3116 chip, providing powerful and clean Class D amplification. This combination allows for a detailed and immersive musical experience with both warmth and precision.
