T-Phonum 2 MM/MC Phono PreAmplifier with JRC 5534D Op-Amps, RIAA Equalization, Dual Power Supply, Kits Board

Elevate Your Vinyl Listening with Audiophile-Grade Phono PreamplificationT-Phonum 2 Phono Amplifier is a high-performance preamp designed to bring out the best in your vinyl records. Whether you use Moving Magnet (MM) or Moving Coil (MC) cartridges, this preamp delivers precise RIAA equalization, low-noise amplification, and transparent sound reproduction for a true audiophile experience.Key Features: Universal MM/MC Support: Switchable gain settings (+40dB / +64dB) and loading options ensure compatibility with nearly all turntable cartridges, from budget-friendly MM to high-end MC designs.Top-Tier Component Selection: Built with JRC 5534D op-amps (with sockets for customization), NIPPON CHEMI-CON, WIMA, and NXP capacitors, and 1% precision metal film resistors for exceptional audio clarity and accuracy.Stable Dual Power Supply: Requires an AC 15-0-15V transformer (not included) for ±15V DC power, regulated by LM7815/LM7915 ICs to eliminate noise and hum, even in high-gain MC mode.User-Friendly Design: Features DIP switches for easy configuration, terminal blocks for simple connections, and optional DIY assembly for electronics enthusiasts. The compact PCB fits easily in most audio enclosures.Built to Last: All components are rated for long-term reliability, with electrolytic capacitors rated at 35V and film capacitors at 50V/63V to handle typical audio system voltages.

• MM/MC Dual Compatibility：Designed for both Moving Magnet (MM) and Moving Coil (MC) cartridges, this phono preamp offers selectable gain (+40dB for MM, up to +64dB for MC) to accommodate a wide range of turntable setups. Tuned for audiophile-grade RIAA equalization to restore your vinyl's original sound.
• Premium Audio Components：Features four JRC 5534D operational amplifiers, NIPPON CHEMI-CON electrolytic capacitors, and WIMA/NXP film capacitors for low noise and transparent sound reproduction. Uses 1% precision metal film resistors for accurate signal processing.
• Balanced Dual Power Supply：Built for ±15V DC dual power supply (AC 15-0-15V transformer required, not included), with LM7815/LM7915 voltage regulators and FR207 diodes for stable, clean power delivery to eliminate hum and interference.
• Welding is simple: there is a detailed product list and explanatory diagram.DIY Friendly for All Skill Levels.
• Compact & Reliable Build：The yellow PCB design ensures efficient heat dissipation and signal isolation, with electrolytic capacitors rated at 35V and film capacitors at 50V/63V for long-term durability. Ideal for use with all turntables that lack a built-in phono stage.
