Conrad Johnson ET-3SE Pre Amp

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 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 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 push buttons 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.
