ET3 Pre-Amplifier

Conrad Johnson ET3
 The ET3 line-stage is a “baby” version of Conrad Johnson’s flagship line-stage preamplifier, the GAT. With voltage gain provided by a triode vacuum-tube, the zero-feedback line-stage circuit of the ET3, along with its DC voltage regulators, closely replicates the circuit of the GAT.
Finally, and especially noteworthy, the ET3 features a relay operated discrete stepped attenuator level-control circuit of the type found in the GAT and CT5, absent only the balance control function found in those more costly models.

Functionally, the ET3 provides highly flexible I/O facilities with six separate line-level inputs (including one “tape” loop), plus a theater loop that facilitates use in a home theater system. In addition, the ET3 offers the convenience of infrared remote control of all functions. For vinyl enthusiasts, the ET3 is optionally available with a vacuum-tube phono stage that borrows its zero-feedback audio circuit from our reference quality TEA1 phono stage.

Every conrad-johnson ET3 Preamplifier is patiently and carefully hand assembled, then individually inspected and its performance verified by an experienced audio technician.
