Description

A slim mid-seventies Marantz integrated amplifier, through our Level 1 service, in very good condition, with a phono stage, a three-band tone section and a microphone input on the front panel.

What it is

The 1070 belongs to the slim-chassis family Marantz built in the mid-seventies alongside the 1060 amplifier and the 112 tuner, all sized to sit in the same wood case. It is rated at 35 watts per channel into 8 ohms across the full 20 Hz to 20 kHz band at 0.3% distortion, and it carries a proper MM phono stage for your turntable. Designed in the USA and built in Japan, 1975 to 1978.

The front panel gives you more control than most amplifiers of its size. The tone section has three sliders, bass, mid and treble, where most of its rivals stopped at two, so you can shape the vocal range without touching the bottom or top end. There are high and low filters for noisy records and rumble, a loudness switch, a balance slider, and a mode selector that runs left, right, stereo, reverse and mono. The input selector takes a microphone as well as phono, tuner, aux and two tape decks, with a front-panel mic jack beside the headphone socket.

Around the back, the preamplifier and power amplifier sections are linked by pre-out and main-in jacks, so they can be separated to add an equalizer or to use either half on its own. Both tape loops have RCA jacks and a DIN socket. There are terminals for a main and a remote or ambience pair of speakers, a chassis ground post, and two AC outlets, one switched and one unswitched, for a turntable or tuner.

It is shown bare, in its factory black metal case. If you would like it in wood, a walnut-grain cabinet sized for the 1070 is listed separately.

The service it has had

Level 1 service, carried out on our bench:

  • Every input, output and control tested
  • All pots and switches deep-cleaned and deoxidized
  • Any blown indicator lamps replaced
  • Power supply wiring checked and cleaned
  • Burn-in and sign-off testing
  • A second bench test by a different tech before listing

Condition

Very good, and free of significant marks. The brushed silver faceplate, the knobs and sliders, the panel legends and the black case all present well, as the photographs show.

A clean, fully serviced mid-seventies Marantz in the slim chassis, with the controls of a much bigger amplifier.

🎚️ Gold Series RCA Interconnects

Our own Gold Series RCA Stereo Interconnect is a shielded, gold-plated stereo pair, in stock and ready to go. It is the cable that connects this to the rest of your system, and it is a straightforward upgrade on the free leads that come in the box with most equipment. 👉

🔌 Speaker Cable, Built on Our Own Bench

We hand-build speaker cable here in any length you need — pick the gauge and the terminations on our Custom Speaker Cable Builder. We also make our own gold-plated banana plugs, spades and pin connectors if you would rather terminate cable you already have. 👉

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

The 1070 was built decades before Bluetooth reached home stereo, and it does not need replacing to get it. Our own RA-Twin II adapter plugs into the aux or a 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 less than buying the two separately. 👉

⚠️ 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.
