JOYCRAFT DIY Series The OA-JC1 Digital Power Amplifier with Vacuum Tubes employs a precise two-stage amplifier configuration. The first stage uses the "12AU7," RCA's representative vacuum tube model that emerged around 80 years ago, as its core, providing a smooth and rich tone to the system. The amplifier's subsequent stage utilizes the Texas Instruments TPA3116, a Class D amplifier known for its excellent power, precise output, and clean delivery. This further enhances the enjoyment of music with even greater detail.
