Introducing our state-of-the-art stereo preamplifier. Along with almost unmeasurable noise and distortion (typically 0.0003% THD+N!) it sports remote volume control, input selection and muting plus bass and treble adjustment knobs on the front panel. Now let’s build the input selection boards and power supply.


  • Very low noise and distortion
  • Remote controlled input selection and volume control with muting
  • Manual volume control plus bass and treble cut/boost controls
  • Tone control defeat switch bypasses bass and treble controls
  • Minimal interaction between tone controls
  • Can be used with just about any power amplifier, including our Ultra-LD series and the 20W Class-A amp
  • Designed to be mounted in the front of a stereo amplifier chassis, but is also suitable for standalone use
  • Three status LEDs
  • Runs from ±15V DC
