Vintage Marantz stereo equipment is highly coveted by audiophiles for its warm, musical sound, iconic gyro-touch tuning wheels, and timeless faceplate aesthetics. To keep these classic 1960's through the 1990's units performing at their best, they require precise component-level calibration and expert servicing. At Frotronics, we specialize in complete workbench diagnostics, total recapping, and rigorous restoration of classic solid-state Marantz gear, ensuring your investment retains its legendary acoustic qualities and high market value.

​

Even the robust build quality of classic Marantz gear eventually succumbs to component degradation over forty-plus years. Our bench service directly tackles common Marantz issues, including replacing dried-out or leaky original capacitors, upgrading failure-prone vd1212 diodes, repairing erratic differential input transistors, failing output transistors, and restoring dim or failing illumination with vibrant lighting. We completely clean noisy potentiometers and switches to entirely eliminate popping, scratching, and channel dropouts.

Please contact us with your model number to see if we can restore your equipment. Since there are so many models made by MARANTZ it is hard to list all the units we service.
