Shop Demo unit is in excellent condition. This is a line level only, no phono stage

This ‘special edition’ preamp, the ET3SE comes with a big helping of Conrad-johnson’s specialist parts, as does the matching ETPHSE phono stage option. As you’d expect, Conrad -johnson’s favoured Teflon capacitors replace polypropylene types in crucial locations. In the line stage, these include the output coupling bypass, the main storage bypass capacitor and the voltage reference filter capacitor. Many resistors are upgraded to Vishay types and these include the 100ohm input and output damping resistors, and all 26 volume control resistors. Grid load resistors in the line stage are upgraded to Cadduck. Similarly, in the ET3SE phono stage the interstage coupling capacitor, power supply storage capacitor and current source filter are upgraded to Teflon. Again, in the phono stage, the input and output damping resistors are upgraded to Vishay parts. Input and output RCA (phono) connectors are upgraded to a discrete hand-wired type.
   Rotary volume controls disappeared from Conrad-johnson’s vision years ago, and so the ET3SE fascia carries the now-familiar combination of up-and-down pushbuttons and circular display window. This gives a numeric display of volume settings from 0 to 99, these representing the attenuator’s 0.7dB steps. This resolution is fine enough for any but the most neurotic level-tweaker.
   This model has no balance control to adjust the relative level of L/R channels, so although the two figures displayed seem to represent the two channels, they can in fact only change in unison.
