DESIGNED IN USA, MADE IN JAPAN

Top of the line 1982-1984 Marantz integrated amplifier model (PM-25, PM310, PM350, PM450, PM510DC, PM550DC, PM750DC)

North America version, all 24K gold plated connectors and shielded power transformer. See the pictures. The world voltage version is different.

VERY NICE, SUPER CLEAN, SERVICED, ORIGINAL NEVER REPAIRED COLLECTIBLE CONDITION, WORKS AND SOUNDS LIKE NEW Hard to find like this

The service manual indicates this model was done by Superscope, not Philips. This means it's still classic Marantz. Classic transistor amp design sound is smoother/sweeter than almost all newer IC chip based amps.

It will be tested for a local Ottawa buyer at the front door with record player and CD player. Can be shipped; keep reading.

Basic maintenance service done 08/2022:

* Taken apart * Cleaned and detailed in and out * All controls, switches, contacts, RCA jacks and potentiometers deoxed/lubed using pro grade D100/F5/G5 ($126/3 cans); * Relay cleaned; * Bias voltages adjusted to factory specs for best sound/amp stability = 8mV L/R at 1 min after power up; (very important for famous correct Marantz sound) * LED power meters adjusted to factory specs; * FM MPX adjusted for best sensitivity/separation and reception in Stereo * Re-assembled * Fully tested at full power with all inputs for stable oscillation-free performance

Gorgeous sweet and clear Marantz sound!

MARANTZ PM 750DC

* High current design, somewhat similar to 1979-1985 higher end Harman Kardon models * All-metal case/front panel * Exotic gold/champagne Esotec finish * Premium all-discrete oversized power transistors: Sanken (2SA1187 + 2SC2838) x 2 pairs (also employed in Denon PMA-750 and high-end Japan-only zero-NFB Pioneer M-Z1, M-Z1a Class A monoblocks); The replacement transistors are still readily available for those; see links below.

* Pure DC Power Amplifier stages (similar to Sansui G series), for powerful and dynamic low frequency response with zero phase distortion; * Heavy duty Marcon filter capacitors for power supply; * Best quality Elna Audio and Nippon Chemi-con capacitors in signal path; * Liquid cooling (heat piping, same as 80's Luxman); * Very cool Green 'n' Red LED power meters; * Gold plated RCA jacks; * Complete circuit protection: DC relay and 4-fuses

* Rated power output RMS: 80 + 80 Watts (into 8 Ohms 20-20KHz) * Rated power output RMS: 115 + 115 Watts (into 4 Ohms 20-20KHz) * Meters rated at: 280 Watts into 4 Ohms (to show dynamic power) * Label: 400 Watts * Normal home listening levels: 0.1W to 5 Watts output; at 5 Watts it's already very loud

* Frequency response: 5 - 75,000 Hz * THD: 0.03% (at full power), less than 0.007% at 1 Watt output * IMD: 0.03% (at full power), less than 0.007% at 1 Watt output * Damping factor: 85 * SNR: 85dB (MM), 98dB (line) * Input sensitivity: 0.28mV (MC), 150mV (line) * Output: 410mV (line) * Dimensions: 416 x 117 x 329mm * Net Weight: 9 KG

* Speakers: A, B, A+B, Off; 2 pairs of 8 Ohm speakers or 1 pair of 4 Ohm speakers * Headphones jack * Phono 1 MM, Phono 2 MM/MC, Aux1, Tape1/Aux2, Tape2/Aux3, Tuner/Aux4 * Tape Monitor 1 * Tape Monitor 2 * All inputs except Phono are technically Line inputs and can be used for anything - PC, iPod, phone, TV, CD player,.. * Integrated 10-band EQ (no need for an external equalizer anymore!) * Tone defeat (EQ Defeat) * Subsonic Filter * High Filter * Loudness * Bass, Treble * Volume, Balance * Stereo/Mono switch * EQ Out 1/4 inch jack (to make equalized tapes) * Rec out (rotary switch) for all inputs: you can listen to any source while recording another * 2 extra power outlets: 1 switched, 1 unswitched

The 550DC and the 750DC: The circuit design is very similar. Both amps sound similar to Marantz 1550, Marantz 2265B, Marantz 1152DC. That sonic signature is different from pre-1977 Marantz: much more clear/transparent to the source; The clarity is simply amazing.

QUOTES (Google search):

"So it all looks good, but best of all the nice surprise is that is sounds REALLY nice :music:. A bit like the Yamaha CR-820 I restored, a lively dynamic sound, very pleasant, good bass as well !"

"I have to say this one sounds REALLY nice to me after recap. And that'paring it to pieces (restored as well) like a Yamaha CR-820, a Marantz 1060, a 2220 and my modern Marantz PM8005 :)"

"Sorry for late answer, I've been busy for some timePM550DC is a great amp. I had it for a while, paired with ST310 in system B: The sound from that old amp was fabulous - new amps can'e even close to it. I am always sad when I have to sell something, but parting from that piece was THE biggest mistake I've ever made..."

"The Sound of Marantz is pelling warmth of a Stradivarius. It is a dancing flute, a haughty bassoon and the plaintive call of a lone French horn. The Sound of Marantz is the sound of beauty, and Marantz equipment is designed to bring you the subtle joy of its delight. Wonderful adventures in sound await you when you discover that the Sound of Marantz is the sound of music at its very best."

****************************************************************************************** Local buyer much preferred (cash on pickup); e-transfer is possible, but unpredictable, takes from 2 min to 30 min waiting to go through. I will ship in Canada if paid by Interac e-transfer, packed nicely with PP foam/styrofoam, insured and tracked. Shipping costs: $45 ON/QC, $56 to Alberta, $65 to BC Pickup or shipping only, no deliveries.

Shipping outside of Canada is possible only if paid by instant MoneyGram or WU money transfer service; or US cash (at current Google exchange rate) sent by Priority/Xpress registered mail, preferably with signature; nothing else.

I've been collecting vintage stereos for a long time, so trade-ins, old receiver, amplifier, CD player, speakers, turntable in any condition will be considered.
