VINTAGE MARANTZ STEREO RECEIVER
MARANTZ TWENTY SEVEN / MARANTZ 27
 #...4476
 Circa 1970-73
 MIJ

for sale
SOLD 11/5/12
SHIPPED TO SOUTH DAKOTA

Our technician has completely gone through and 'Certified' this unit. Everything was cleaned inside and out including all contacts, switches, controls and I/O jacks. All internal fuses checked for correct values and replaced where necessary. He replaced the questionable power switch. All dial & meter lamps were replaced, as well as the 'stereo' indicator with new bulbs, for trouble-free service. We also aligned the tuner for optimum performance on both AM and FM including realigning the 'local osc'. AM reception on this Marantz 'Twenty Seven', #...4476 is above average. VERY GOOD TUNER! FM reception as well great and IMPECCABLY CLEAN!!! Dial pointer track was cleaned of old lube and re-lubed w/ silicone grease. Output bias adjusted correctly for clean output. DC offset adjusted to less than 2mV / Ch. All functions tested for perfect operation. Power supply adjusted to correct voltage. All inputs tested and both sides produce clean and even sine waves! Tone control shafts have a bit of 'play' in the bushings, but simply from 30+ years of age (short of replacing them, they are what they are, and still function fine electronically). Following restoration procedures, the unit was run at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours. All functions test perfectly. 
Following electronic refurb, entire unit was cosmetically detailed inside and out. Only 'cosmetic' issue is light 'splotching' on the wood case, but nothing too distracting (see photos above). Total restoration time investment ~7 hours.
  

 On our test bench, this unit of this Marantz Twenty Seven / 27 receiver #...4476,  amplifiers produced 16.4 volts @ 8 Ω per channel for 33 Watts / channel and 12.8 volts @ 4 Ω per channel for 41 Watts / channel via discrete, TO-3 style, Original Motorola metal cased output devices at 1khz. (2x 2SJ2008 & 2X 2SJ2009)
AC current at idle measured at 100mA. DC offset adjusted to produce <2mV. Bias set correctly for clean sine waves and correct draw.

 Again, as stated before, we have completely gone through this Marantz Twenty Seven / 27, Stereo Receiver cleaning and testing all and it gets our full 'Certification'. With the exception of the above mentioned, 'splotching' to a section of the wood case (see photos above) the unit is near perfect cosmetically. The brushed aluminum face and all original, milled knobs in great shape. After restoration, receiver looks, performs and sounds great! This unit features Marantz's 'Variable Overlap Drive' technology, to virtually eliminate crossover distortion. In addition, this circuit compensates for internal component 'aging' insuring 'like new' performance for many years to come. According to an original Marantz Twenty Seven Brochure states;
"The Model 27 delivers 60 Watts RMS. Most receiver manufacturers measure power by such ratings as 'Music Power' or 'Peak Power'. Marantz measures power by the only reliable method - RMS power. Marantz 60 watts sounds more powerful than 180 Watts music power, because Marantz power is delivered throughout the entire audio spectrum, from 20Hz-20kHz (both channels driven), at or below the rated distortion. Marantz guarantees that you receive 60 Watts RMS."  This is a VERY 'Musical' sounding tuner/pre/power-amp. Very 'full, warm and phat'. Great 'low-end' depth at any volume. Tone controls have a lot of influence. Overall a pleasing unit to listen to in all aspects. Measures 15" wide x 16.5" deep x 7" high and weighs 35 lbs unpacked. Includes our standard 90 day limited warranty!

Our technician has completely gone through and 'Certified' this unit. Everything was cleaned inside and out including all contacts, switches, controls and I/O jacks.

SOLD 9/19/12
SHIPPED TO CALIFORNIA

Our technician has completely gone through and 'Certified' this unit. Everything was cleaned inside and out including all contacts, switches (requires extensive removal of front chassis assembly and circuit boards), controls and I/O jacks. All internal fuses checked for correct values. He disassembled and 're-built' the power switch (as the original is better than the substitutions available). He also replaced the original, and frayed tuner dial string with new, and proper dial cord (never an easy operation). All indicator lamps checked, and most replaced proactively and all 8 dial & meter lamps were replaced, as well as the lamps in the 'dial pointer' with new bulbs, for trouble-free service. We also aligned the VERY sophisticated tuner for optimum performance on both AM and FM. Dial pointer track was cleaned of old lube and re-lubed w/ silicone grease. We also replaced a 'questionable' 'Speaker A' output clip with original. Output bias adjusted correctly for clean output as well as the DC offset to a low level. He also upgraded a fairly 'questionable' AC power cord with a heavy, 3-Prong, grounded one. All functions tested for perfect operation. Power supply adjusted to correct voltage. Output transistors removed and fresh heat sink compound applied. All inputs tested and both sides produce clean and even sine waves! Tone controls are super quality, Alps brand, "full-size", de-tented potentiometers. As the original face plate on this unit had a few minor scuffs, we replaced it with a clean, original Marantz 2245 faceplate from a 'donor' unit we had.
Following restoration procedures, the unit was run at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours.

He also replaced the original, and frayed tuner dial string with new, and proper dial cord (never an easy operation). Found another previous, 'non-factory' mod to the 2 / 4 channel power amp selector and restored to original 'schematic design'. All indicator lamps and all 8 dial & meter lamps were replaced, as well as the lamps in the 'dial pointer' with new bulbs, for trouble-free service. We also aligned the VERY sophisticated tuner for optimum performance on both AM and FM. Generally AM reception in a stereo receiver is treated as an 'after thought', but the AM reception on this Marantz 4240, #...0302 is WAY above average (frankly it's amazing). VERY GOOD TUNER! FM reception as well great and IMPECCABLY CLEAN!!! Dial pointer track was cleaned of old lube and re-lubed w/ silicone grease. We also replaced a 'questionable' 'Speaker A' output clip with original. Wave form issues with driver boards / outputs corrected. Output bias adjusted correctly for clean output as well as the DC offset to a low level. All functions tested for perfect operation. Power supply adjusted to correct voltage. Output transistors removed and fresh heat sink compound applied. All inputs tested and both sides produce clean and even sine waves! Tone controls are super quality, Alps brand, "full-size", de-tented potentiometers. As the original wood grain metal case had some issues, we had it chemically stripped by a furniture refinisher and a coat of 'pro' quality primer laid down, followed by a couple of coats of black 'hammer-tone' finish. Looks nice.
Following restoration procedures, the unit was run at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours.
Following electronic refurb, entire unit was cosmetically detailed inside and out. All functions test perfectly. Total restoration time investment ~20+ hours.
  

 On our test bench, the amplifiers of this Marantz 4240 receiver #...0302, in '2-Channel' mode, produced 26 volts @ 8 Ω per channel for 87 watts / channel. In '4-Channel' / Quadraphonic mode each channel produced 15 volts @ 8 Ω for 32 x 4 watts and 13 volts @ 4 Ω for 42 x 4 watts
via discrete, TO-66 style, original metal cased output devices at 1khz. (8x 2SD315E)
 AC current at idle measured at 0.3A.
DC offset adjusted to produce <0.2mV out of any of the 4 channels. Bias set correctly for clean sine waves and correct draw.
