Description

A Marantz 2245 from the golden age of the receiver, serviced and ready to work.

The case, and the upgrade you can choose

This 2245 wears its original Marantz case — the vented woodgrain top and wrapped sides the receiver left the factory in — and it has held up well. That is the unit as Marantz sold it, and for most buyers it is exactly right.

If you want to take it further, the walnut WC-22 was the factory’s own upgrade cabinet, and our woodworker builds a cherry cabinet in that spirit for these receivers: Ottawa Valley cherry, resawn into veneer and book-matched so the grain runs unbroken across the sides, hand-finished with linseed oil and beeswax. It turns a classic receiver into a piece of furniture. Ask and we will quote it for you.

Made in Japan Marantz 2245 Stereophonic Receiver — classic 70s hi-fi with warm, detailed sound

The Marantz 2245 represents the golden age of hi-fi audio from the iconic Japanese manufacturer. Produced from 1971 to 1976, this mid-level receiver struck the balance between functionality, power and aesthetic appeal that made the line famous. Known for the warm, friendly tonal balance that set Marantz receivers above other solid-state units of the era, the 2245 delivers a smooth, detailed soundstage with tight bass response and engaging midrange presence.

This versatile receiver provides ample power for most speaker setups, often delivering more than its advertised wattage when pushed. The beautiful blue-lit gyro tuning dial and elegant brushed aluminum faceplate make it as visually appealing as it is sonically impressive. Perfect for powering your vinyl setup, it includes a high-quality phono stage for moving magnet cartridges, along with multiple auxiliary inputs and a tape loop.

The 2245 features pre-out/main-in connections, allowing for system expansion with external processors or additional amplification. With its combination of power, flexibility and Marantz’s legendary build quality, this receiver remains highly sought after by vintage audio enthusiasts and collectors alike.

🔌 Radique Audio Pin Connectors — Made For Exactly These Terminals

The 2245 uses Marantz’s original pressure-clip speaker terminals, and it drives two pairs, MAIN and REMOTE. Bare wire frays and works loose in a clip like that, and a rigid banana or spade levers on a forty-year-old terminal. Our own Gold Plated Pin Connectors were designed for this job — the pin flexes instead of sitting rigid, two set screws hold the wire instead of one, and the jackets are colour-coded. They take 12 to 18 AWG, in 1, 2, 4 or 10 pairs. We also hand-build speaker cable here in any length and will terminate it in pins for you — pick the gauge on our Custom Speaker Cable Builder. 👉

🪵 Dress It in Ottawa Valley Cherry — Built by Our Own Woodworker

Marantz sold the walnut WC-22 as the factory’s own upgrade cabinet for these receivers. We build the same idea in Ottawa Valley cherry — resawn into veneer and book-matched so the grain runs unbroken across the sides, hand-finished with linseed oil and beeswax. This 2245 already wears its original case and looks right as it is; the cherry is the step beyond. Ask and we will quote it with the receiver. 👉

📶 Add Bluetooth — The RA-Twin II, Built For Exactly This

The 2245 was built before Bluetooth existed, and it does not need replacing to get it. Our own RA-Twin II adapter plugs into the AUX or tape input on the back and streams from a phone, tablet or laptop — nothing modified inside, and it comes with a starter cable so it works out of the box. If you want it done properly, the Gold Series RX Bundle pairs the adapter with our shielded Gold Series 3.5 mm to Dual RCA cable for $69 — $19 less than buying the two separately. The RA-Twin II transmits as well as receives, so it will also send from this receiver out to wireless headphones. 👉

⚠️ Important Information for International Buyers

This unit is configured for North American 110/120V power. Buyers outside North America will require a step-down transformer and appropriate plug adapter.

About brand

Marantz at Radique

Marantz began in 1953 in Queens, New York, where Saul Marantz built tube preamplifiers and amplifiers, and by the 1970s it was making receivers with champagne-gold faceplates, blue-lit dials and flywheel tuning. We carry Marantz receivers, amplifiers and preamps, turntables, tuners, CD players and cassette decks. We've had more than 150 Marantz listings so far, covering nearly 100 different models. Every used Marantz here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Many Marantz components were sold without their wood case, so we also make new cherry WC-22 and WC-10 style cabinets. Don't see the model you want? Tell us on First Dibs and we'll email you when one arrives.

Our five best-selling Marantz models so far: the SR4023 stereo receiver, the vintage 2225, the SR7000 AV receiver, the SR4320 stereo receiver and the vintage 2238B.

The Marantz story, 1953 to today

Saul B. Marantz founded the company in New York in 1953. His first product, the Audio Consolette preamplifier, became the Model 1, and Marantz dates the first Consolettes to 1952–53. Marantz says the early factory was in Woodside, Queens.

The tube years. Through the late 1950s and early 1960s Marantz built a small run of tube separates in New York that collectors still chase: the Model 7 preamplifier (1958), the Model 9 power amplifier (1960) and the Model 10B tuner (1964).

Superscope and the move to Japan. In 1964 Superscope, the company that also distributed Sony tape recorders in the US, bought Marantz, and Saul Marantz resigned at the end of 1967. The Model Eighteen of 1968 was the first Marantz receiver, rated at 40 watts per channel. Under Superscope, design moved to California and, from the late 1960s, production moved to Japan through Standard Radio, which became Marantz Japan in 1975. Receivers such as the 2230 and 2270 are listed as designed in the USA and produced in Japan.

The power race. After a 1974 Federal Trade Commission rule tightened how amplifier power was rated, receiver makers competed on watts. Marantz's Model 2500 of the late 1970s was rated at 250 watts per channel and had an oscilloscope tuning display.

Philips, Denon and today. In 1980 Philips bought Superscope's stake in Marantz Japan and the brand outside the US and Canada. Marantz says its CD-63 of 1982 was one of the first CD players, and its "KI Signature" models carry the initials of Ken Ishiwata, who joined in 1978. In 2001 Marantz Japan bought the trademark back from Philips, and in 2002 it combined with Denon to form D&M Holdings. In September 2025 HARMAN, a Samsung company, completed its purchase of Sound United, the parent of Marantz and Denon.

Which Marantz is which?

Tube separates (1950s–60s): the Models 1, 7, 8B, 9 and 10B, built in New York. Rare collector pieces.

First receivers (from 1968): the Model Eighteen, followed by the Nineteen at the end of 1969.

22xx receivers (from 1972): the first set was the 2215, 2230, 2245 and 2270, with the champagne-gold faceplate, blue-lit dial and "Gyro-Touch" flywheel tuning. A higher number generally means more power: the 2230 is rated at 30 watts per channel, the 2270 at 70. Later "B" versions such as the 2220B and 2285B followed.

Big late-1970s receivers: the 2325 (125 watts per channel), the 2500 flagship and four-channel "Quad" receivers.

1000-series integrated amplifiers: for example the 1060 (30 watts per channel, from 1971), the 1070 and the 1150 (75 watts per channel). The slim 1030, 1040, 1060 and 1070 share their case size with tuners such as the 104, 105 and 112.

Tuners: from the tube Model 10B to solid-state models such as the 2130, with its oscilloscope display.

Wood cases: Marantz sold its wood cases separately: the WC-22 for the 22xx receivers, the WC-10 for the slim 1000-series amplifiers and 100-series tuners, and the WC-1 for larger models such as the 1200. That is why so many turn up bare. A customer who sold Marantz in Ontario in the 1970s told us the cases his shop ordered were built here in Canada, by Westinghouse. Our own cherry WC-22 and WC-10 style cabinets are made in Canada too.

CD players: from the CD-63 of 1982 to the KI Signature versions.

Buying used Marantz: what to check

Dial and meter lamps. Burnt-out bulbs are common on 1970s receivers and are often replaced, sometimes with LEDs. Ask which, if the look of the dial matters to you.

The dial itself. The diffuser sheet behind the dial ages and can dull the glow. Check that the Gyro-Touch pointer moves smoothly and tracks the stations; dial cords are a common replacement part.

Controls and switches. Crackle when you turn a control or work a switch usually means dirt. Try every input, and walk away from a unit that drops a channel.

Capacitors and bias. Electrolytic capacitors in 1970s gear are often past their best, and full restorations replace them. Restorers also set the bias and DC offset.

Cosmetics. Pitting on the faceplate points to damp storage, and dents or water stains to rough handling.

Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
