Introducing the Marantz Gold Plate Service
Your vintage Marantz 22xx or 23xx series receiver is a masterpiece of classic audio engineering—beautifully built, great sounding, and designed in an era when quality mattered.
Many of these legendary receivers are now approaching or exceeding 50 years old. While they were built to last, age eventually takes its toll on capacitors, relays, lamps, switches, connections, solder joints and other components.
At Stereo Lab, we’ve combined many of the most important maintenance and restoration procedures into one comprehensive package:
The Marantz Gold Plate Service
In most cases, the Gold Plate Service will restore your Marantz to reliable, great-sounding operation while preserving as much of the original receiver as practical. If we discover problems beyond the scope of the package, we’ll discuss them with you before performing additional work.
Gold Plate Service Includes:
Clean all controls and switches, including the pre-main loop.
Treat connections with CAIG DeoxIT as appropriate.
Replace lamps with LEDs in your choice of blue or white, including indicator lamps as needed.
Install a new LED stereo beacon.
Clean and lubricate the tuning capacitor.
Replace the speaker protection relay.
Replace power-supply capacitors included within the service package.
Test critical capacitors and replace as needed within the scope of the service.
Center the FM discriminator.
Peak FM IF coils.
Clean and polish the faceplate.
Clean and DeoxIT rear RCA connections and speaker terminals.
Clean and dress rear-panel connections.
Test all inputs, including the phono section.
Inspect for more serious problems that may require additional repair.
Inspect for broken or cold solder joints and reflow as needed.

Replace missing feet with new 3-D printed feet as needed.
Replace a frayed, damaged or cut power cord with an equivalent cord as needed.
180-day warranty on Gold Plate service work performed by Stereo Lab.
Priority Service — your Gold Plate receiver goes next on the bench rather than entering our normal 8–10 week service backlog.
$599 + Tax
Important Gold Plate Service Terms
The Marantz Gold Plate Service is available only for qualifying Marantz 22xx and 23xx series receivers. Quadraphonic models and models outside these series are not eligible.
Problems discovered outside the services described above are not included in the $599 package price. If additional repairs are necessary, they will be estimated separately and discussed with you before additional work is performed.
“Next on the bench” means that once the technician completes the unit currently being serviced, your Gold Plate receiver is next in line. It does not mean immediate or same-day completion.
Bring your classic Marantz to the people who know vintage audio.
