audio research d76 in excellent condition
This is a very nice D76. It was sent to Audio Research for service. It received all new filter caps and all new tubes, and a new shipping box. I checked the tubes and bias. Bias is spot on and the tubes test better than new. The output tubes are Svetlana Electronic Devices (SED) before the New Sensor/Winged C legal action. Output tubes are 1995 date code, and matched by Audio Research. Wired for 120V. This is a great sounding, clean amplifier, with the correct green power lens. If you're looking for a D76, you are hard pressed to find a nicer example. Hook it up and enjoy.

audio research ls3 preamplifier
For your consideration, a fine example of an Audio Research LS3 preamplifier. This solid state preamp has a few nicks, but overall looks quite good. In the picture of one side there is a spot that looks like rust; this is a symptom of my terrible photography skill. There is a blemish in the finish, but it is not rust. The LS3 was a Stereophile Class 'A' component. Specifications (borrowed from the ARCDB website): Frequency response ±.5 dB, 2.0 Hz to 100 kHz. -3dB points below 1 Hz and above 200 kHz Distortion (THD) Less than .01% at 2V RMS output. (Typically less than .005% in midband) Noise & hum 18 µV RMS maximum IHF weighted noise at main output with gain control minimum (more than 100 dB below 2V RMS output, or 4V balanced output (LS3B)) Gain Main outp...
