ET3SE Vacuum Tube Preamplifiers With High Gain SE Tube Phono Stage and Machined Alumimum Remote. 

At conrad-johnson, development of our flagship products has traditionally led to important enhancements of our entry-level offerings.

The ET3 preamplifier is a case in point. The ET3 line-stage is a “baby” version of our flagship line-stage preamplifier, the GAT. The family resemblance is much more than skin deep.

The ET3SE boasts CJD Teflon capacitors in critical circuit applications, dozens of upgraded metal foil resistors (including ALL resistors in the stepped attenuator level control), upgraded machined input/output connectors, and even an upgrade AC mains line-cord.

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 ET3SE is optionally available with a SE High gain vacuum-tube phono stage that borrows its zero-feedback audio circuit from our reference quality TEA1 phono stage.

Less than 50 hours use.
