The Wright Audio
PH - 3 Phono Stage
with PS - 3 Separate Tube Power Supply
The Wright Audio PH – 3 Phono Stage provides the additional amplification and equalization neccessary to accept the output from a turntable equipped with a moving magnet or high – output moving coil cartridge.
The separate tube power supply eliminates all mechanical and electrical interference from an internal power supply. In addition, there are separate Left and Right Channel tube power supplies for increased channel separation resulting in more accurate sonic imaging and dimensional sound. Use of a choke-filtered tube power supply also seems to increase the sound’s apparent purity and resolution.
A manual ‘mute’ switch is included which can prevent transient pulses created when the stylus is placed on or taken off the record.
An hourmeter is provided to keep track of elapsed time on the tubes and provides a rough approximation of stylus time.
The power supply can accommodate a second PH – 3 Phono Stage for another or a different player setup.
All parts in the Preamplifier and Power Supply are extremely conservatively operated at a small fraction of their rating for very long life.
This uniquely musical component presents an even top to bottom frequency balance, great clarity and an excellent soundstage which will have you rediscovering your vinyl collection!
