Conrad Johnson - ET6 - Preamplifier

ET6/ET6SE Vacuum Tube Preamplifiers At conrad-johnson, development of our flagship products has traditionally led to important enhancements of our entry-level offerings. The ET6 preamplifier is a case in point. The ET6 line-stage is a “baby” version of our flagship line-stage preamplifier, the GAT. The family resemblance is much more than skin deep. With voltage gain provided by a triode vacuum-tube, the zero-feedback line-stage circuit of the ET6, along with its DC voltage regulators, closely replicates the circuit of the GAT. Finally, and especially noteworthy, the ET6 features a relay operated discrete stepped attenuator level-control circuit of the type found in the GAT and ET7, absent only the balance control function found in those more costly models. Functionally, the ET6 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 ET6 offers the convenience of infrared remote control of all functions.
