About the ET7-II
The Conrad-Johnson ET7-II, also known as the ET7-S2, is a single-ended tube line-stage preamplifier using one 6922 dual triode for voltage gain and a high-current MOSFET buffer for a low 100-ohm output impedance. Its design incorporates circuit and power-supply developments from the GAT Series 2, a separately regulated DC heater supply, precision relay-switched volume control with 100 approximately 0.7-dB steps, and premium Teflon and polypropylene capacitors. Connectivity includes five single-ended RCA line inputs, two RCA processor loops, two variable stereo outputs, and processor-loop outputs; one processor loop supports unity-gain home-theater pass-through. The unit measures 19 inches wide by 15.375 inches deep by 4.375 inches high and weighs 19 pounds.
