Audio Research Reference 5SE Tube Preamplifier
For sale we have a fine example of the Audio Research Reference 5SE Tube Preamplifier. This unit comes from the original owner. It did not see much use as it has 391 original hours on it. The unit it in perfect working order and sounds exceptional. Physically the unit is in very good condition. There are some small blemishes on the top edge of the faceplate. On the bottom there is a small dent where a universal remote eye was placed. Inside, the preamp is exceptionally clean. Everything looks like new with no bulging caps or heat stressed resistors. Please see the many pictures for further details. The unit presents itself very well and is a statement piece
The display is crisp and bright although it was hard to capture on camera.
The tubes tested like new on our Amplitrex AT1000 tube tester. See results below.

We do not have the original box and packing, however, we will double box the unit and suspend the inner box within the outer using 2" polyethylene foam blocks. We take shipping very seriously, and used only the finest materials to ensure safe transit. Our packing meets and most often exceeds OEM packaging. Pictures of the unit during the packing process will be sent to the buyer when it ships. The unit will ship fully insured, and a signature will be required upon delivery.
SPECIFICATIONS:
Description: Tubed, remote-controlled line preamplifier with six sets of balanced and unbalanced inputs, three sets of balanced and unbalanced outputs, and a unity-gain Processor input. Tube complement: 6550C and 6H30P (power-supply regulation), four 6H30P (dual triodes). Frequency response: 0.2Hz–200kHz, +0/–3dB, at rated output (balanced, 200k ohms load). Maximum voltage gain, main output (single-ended or balanced input): 12dB, balanced output; 6dB, single-ended output. Distortion: 0.01% at 2V RMS, balanced output. Input impedance: 120k ohms balanced, 60k ohms single-ended. Output impedance: 600 ohms balanced, 300 ohms single-ended main, 20k ohms minimum load and 2000pF maximum capacitance. Output polarity: non-inverting. Maximum input: 20V RMS maximum balanced, 10V RMS single-ended. Rated output: 2V RMS (1V RMS single-ended) into 200k ohm balanced load (maximum balanced output capability is 30V RMS at 0.5% THD at 1kHz). Noise: 1.7µV RMS residual IHF-weighted balanced noise output with volume control at "1" (109dB below 2V RMS output). Power consumption: standby, 2W; full output, 130W.
