Vintage Quad Integrated Amplifier
Here is an excellent example of the Marantz Model 4100 Quad integrated amplifier. It can be used as a 4-channel (25 watts x 4) or a 2-channel (60 watts x 2). It also has plenty of inputs, including phono and two tape loops. Minimal service was required to get this beauty back up and running. That service included: replacing the power switch, cleaning all switches and controls, and burnishing the relay.
