Marantz 2226B Stereo Receiver (1977)

The Marantz 2226 is one of the great low powered Marantz receivers. At 26 watts per channel it’s not a powerhouse but the lower powered Marantz receivers are known for their sweet sound. Marantz introduced the 2226 in 1977, and it stayed on the market until 1979.

The 2226 has no more than 0.3% total harmonic distortion and a damping factor of 45. It’s direct coupled amplifier design provides very high damping factors at low frequencies and great low frequency response.


The tuning section has a dual-gate MOSFET FM front end and 3 gang tuning capacitor. It’s a sensitive and very quiet tuning section. It utilizes a phase locked loop (PLL) FM demodulator, and ceramic IF filters and IC amplifier system.


The 2226 has bass, mid and treble tone controls. They’re a Baxandall design which means they focus the boost or cut on the lowest bass or highest treble frequencies. The mid control therefore allows the user more control over the mid range frequencies without affecting the bass or treble much. The balance control is a slider positioned at the center of the face plate. Of course it has the distinctive gyro-touch flywheel tuning knob as well.
