EA-1200 Tube Phono Amplifier By Phasemation

After 9 years, Phasemation has released the new EA-1200 Phono Amplifier, the successor to the EA-1000. Its release immediately follows the release of Phasemation’s flagship EA-2000 and has inherited its rich tones and dimensionality.

A tube LCR non-feedback phono amplifier with independent Lch & Rch composed of 3 units.

1. MC step-up transformer specially tuned based on Phasemation’s T-1000 transformer.
2. Newly designed vacuum tube LCR equalizer circuit, delivering unparalleled transparency and clarity.
3. Reduced noise floor in the power supply, for a blacker background.

The amplifier EQ utilizes independent left and right channel units, supported by an expertly designed power supply, having a very high S/N ratio and high resolution delivering the highest degree of realism and an overwhelming sense of liveliness in the musical performance.

• A transformer based on the Phasemation T-1000 design forms the foundation for three inputs and can be switched to MC or MM for balanced inputs. In addition, Phasemation adopted the BAL/UNBAL switch to counteract ground noise when an unbalanced connection is made on the MC.
• The non-feedback SRPP-type amplifying circuit of the ECC-803S tube has an excellent transient response and an outstanding reputation for sound quality, with a low-impedance output cathode follower using the ECC-802S tubes form a perfect combination sonically. You’ll enjoy the tremendous dynamic range and the kind of glossy and lively sound only possible with vacuum tubes.
• The LCR topology is adopted for the equalizing circuit. Power loss and inductive noise in the signal are minimized, preserving sonic performance by reducing impedance in the signal path. The information obtained is outputted from the last stage without any losses by adopting large coils, high-quality film capacitors, and so forth.
• Three equalizer curve switches are installed. The RIAA for stereo, Mono 1 (for use with DECCA), and Mono 2 (for use with Columbia), enabling higher fidelity playback for mono DECCA and Columbia records.

Power supply featuring direct-heat rectifier 5U4G tubes in a monaural design and with a high-capacity R-core transformer.

The rectification circuit uses an R-core power transformer with excessive capacity creating a rich rectification circuit for independent left and right channels, containing two choke coils and rectifier tubes (5U4G) which in principle do not generate switching noise. Furthermore, the power supply transformer and choke coils are magnetically shielded to provide cleaner and stronger power to the amplifier. In addition, a 3-terminal regulator DC ignition system is used for the heater power supply to achieve a high S/N ratio.

Ensuring Quality
A 10mm-thick aluminum slant front panel based on the elegant design of the EA-2000, a 1.6mm-thick copper-plated steel plate chassis base, and a 2mm-thick aluminum cover with a magnetic shield ensure rigidity and reduce magnetic distortion. The footers are equipped with heavy metal insulators to isolate external vibrations. The RCA terminals are made by Furutech, renowned for their high-quality parts, and the XLR terminals are from Neutrik.
