Conrad Johnson ET3 PH MM Demo Floor Tube Preamplifier Details :

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.
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 PH MM demo come with a vacuum-tube phono stage that borrows its zero-feedback audio circuit from our reference quality TEA1 phono stage.
The ET3 phono stage is built to the same high quality standard found in the ET3 line-stage.
Premium quality component parts are specified to optimize performance and to sustain that performance for years to come.
Precision, metal-film resistors yield low noise performance for greatest clarity. Polypropylene capacitors, used exclusively in the audio circuits and the regulated plate voltage supplies, offer extraordinary temporal accuracy.
