EA-1200 Tube Phono Amplifier By Phasemation

The Phasemation EA-1200 Phono Amplifier is a premium successor to the EA-1000, designed for audiophiles seeking rich tonal depth, dimensional soundstage, and exceptional clarity. Developed after the release of Phasemation’s flagship EA-2000, the EA-1200 builds on its signature warmth and musical realism while introducing several technical enhancements for precise vinyl playback.

This tube-based LCR non-feedback phono amplifier features independent left and right channel circuits, separated into three dedicated units for optimal stereo fidelity.

Key Features

1. MC Step-Up Transformer

• Based on the T-1000 design, the transformer supports three inputs and can be switched between MC or MM modes for balanced connections.
• A BAL/UNBAL switch helps counteract ground noise during unbalanced MC operation.

Advanced Tube LCR Equalizer Circuit

• Uses ECC-803S tubes in a non-feedback SRPP configuration for high transient response and a lively, natural sound.
• Low-impedance output with ECC-802S tubes ensures smooth, dynamic playback.
• Employs LCR topology, minimizing power loss and inductive noise, with large coils and high-quality film capacitors preserving signal integrity.

3. Multi-Curve Equalization

• Three selectable EQ curves: RIAA for stereo, Mono 1 for DECCA, and Mono 2 for Columbia, providing precise reproduction of historical mono recordings.

Low-Noise Power Supply

• Monaural design with independent left and right channels, using 5U4G direct-heat rectifier tubes and a high-capacity R-core transformer.
• Two choke coils and magnetically shielded transformers deliver clean, stable power with minimal switching noise.
• DC regulation for tube heaters ensures an ultra-high signal-to-noise ratio, enhancing transparency and musical detail.

Construction & Build Quality

• Front panel: 10mm-thick aluminum slant design, inspired by the EA-2000.
• Chassis: 1.6mm copper-plated steel base and 2mm aluminum top cover with magnetic shielding.
• Isolation: Heavy metal footers reduce external vibrations.
• Premium connectors: Furutech RCA terminals and Neutrik XLRs for reliable, high-quality signal transfer.

Why the EA-1200?
By combining tube warmth, high-resolution LCR equalization, and a meticulously designed power supply, the Phasemation EA-1200 delivers a dynamic, transparent, and lifelike vinyl experience. With its ability to faithfully reproduce both stereo and historical mono records, it is ideal for vinyl enthusiasts seeking precision, richness, and dimensional sound.

This phono amplifier provides state-of-the-art performance while preserving the musicality and warmth that make tube amplifiers so beloved.
