Audio Research Dual 75 // Stereo Tube Amplifier

SOLD , now part of a Private Collection

With a whopping 75 watts per channel of push-pull tube power, this amazing and rare beast will power almost anything with beautifully fluid midrange without any harshness and deliver the warmth that only a high-end tube amplifier can. All of the tube cages are intact. There are definitely a few scratches on the face that give it a bit of character. Call it patina.
