Tube Phono Preamplifier for Turntable with 6A2 Tubes, RIAA Accurate HiFi Sound, Low Noise, DIYFriendly

BOX X2 Phono Preamplifier with 6A2 Tubes Bring a clean, tubedriven phono signal to your audio system with the BOX X2. Compact and low weight, it provides a dedicated phono preamplifier stage that follows the standard RIAA curve and delivers measurable performance for turntables and DIY audio setups. Key benefits Converts lowlevel phono output to a usable linelevel signal for amplifiers, powered speakers, and recording devices. 6A2 vacuum tubes provide a tube character and tonal shaping while the solidstate design maintains low distortion and signaltonoise performance. Compact footprint and light weight make it easy to integrate into desktop, compact rack, or portable listening setups. Wide mains compatibility through the included power adapter keeps installation simple across international voltages. Features and performance Model: BOX X2 with 6A2 tubes installed. Frequency response: Standard RIAA for accurate phono equalization. Output level: 600 mV when driven by 3 mV input at 1 kHz. Signaltonoise ratio: 98 dB for low background noise. Total harmonic distortion: 0.1 percent for clean reproduction. Input method: 3.5 mm AUX for linelevel input compatibility. Power: DC input 12V. Includes adapter with output 12V 1.5A. Adapter accepts AC 110V to 240V. Preamplifier stage improves signal conversion rates for lowlevel cartridges and enhances system gain. Physical specifications Product size: 4.66 inches x 3.85 inches x 1.29 inches. Weight: 0.66 lbs (300 g). Compact metal and tube construction fits small spaces and desktop installations. Typical use scenarios Restore and play vinyl when your amplifier or powered speakers lack a builtin phono stage: connect the turntable to the BOX X2 and route its output to line inputs. Small home or desktop hifi: add tube character to a compact audio chain while keeping noise low and measurements stable. DIY audio projects and experimentation: a compact preamplifier platform for testing cartridges, tube rolling, or building a custom listening setup. Compatibility and installation notes Designed for use with turntables and phonographs that require RIAA equalization and linelevel conversion. Requires a 12V DC supply. Use the supplied 12V 1.5A adapter which accepts AC 110V to 240V mains. Input via 3.5 mm AUX; output connects to standard linelevel inputs on receivers, integrated amplifiers, or powered speakers. The BOX X2 delivers a compact, measurable phono preamplifier solution with tube character and practical features for integration into modern and DIY audio systems.
