Marantz Model 4100

Description

Overview Marantz Model 4100 quadraphonic integrated amplifier — serviced, cleaned, LED lighting installed, and fully tested working. A standout piece from the classic Marantz era, the 4100 gives you the flexibility to run true 4-channel quadraphonic playback or traditional 2-channel stereo, all in one substantial silver-face amplifier with unmistakable vintage presence. This unit is a great fit for buyers building a quad setup, collectors looking for an iconic Marantz conversation piece, or anyone who wants a more unusual flagship-era vintage amplifier than the typical 2-channel receiver. The separate front/rear amplifier sections, flexible routing, and classic Marantz styling make the 4100 one of the more interesting and versatile pieces from the period.
