Marantz 170DC Stereo Power Amplifier * Fully Serviced * NEW Heiukko Solid Wood Case

Marantz 170DC Stereo Power Amplifier * Fully Serviced * NEW Heiukko Solid Wood Case

The Marantz 170DC is a legendary, vintage solid-state stereo power amplifier produced between 1977 and 1980. Highly sought after by audiophiles, it is famous for its iconic brushed-aluminum faceplate, dual illuminated VU meters, and warm analog sound.
Key Specifications
  • Power Output: 86 watts per channel into 8 ohms (continuous)
Total Harmonic Distortion (THD): 0.03%
Frequency Response: 20Hz to 20kHz
Weight: 14.1 kg (approx. 31 lbs)
Design and Circuitry
The Marantz 170DC features a direct-coupled (DC) amplifier design that eliminates transient intermodulation distortion (TIM). It is built with a pure complementary OCL (Output Capacitor-Less) parallel push-pull three-stage Darlington circuit and uses a low-noise dual FET differential amplifier in the first stage. The unit lacks a standalone power switch; it was originally designed to be powered on via the switched AC outlets on its matching preamplifier (like the Marantz 3250B).
