Our technician has completely gone through and 'Certified' this unit.
Everything was cleaned inside and out including cleaning inside and out including all contacts, switches and controls. Output transistors removed and fresh heat sink compound applied. As always, Bias current and DC offset checked for tolerable limits and adjusted when necessary and possible. We also aligned the tuner front-end for optimum AM & FM performance as older internal tuner components have always drifted on vintage gear over the years. VERY GOOD FM TUNER! FM reception incredible, PUNCHY and IMPECCABLY CLEAN!!! All meter and dial lamps replaced for trouble-free service. All inputs tested and both side produces clean and even sine waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine. Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are, into a load with ""Loudness"" on and both Tone Controls at 10 for 48 hours.
  
On our test bench, both this unit's amplifiers produced peak power of 12 volts per channel @ 8 ohms for 18 watts and 10 volts @ 4 ohms for 25 watts per channel via discrete outputs with 1 kHz input. (4x Toshiba 2SC789). AC Idle current at .2A, DC offset output <.54mvDC either channel. Floor noise at 2.0mVAC either channel.

  Wonderful condition, late 70's silver face receiver from Kenwood. Great performance for a 'mid-sized' 2-Channel audio system. This is an INCREDIBLEY ‘Musical’ sounding receiver.

"WORLD AC POWER"
 M.I.J. 

SOLD 5/31/15
SHIPPED TO WISCONSIN

Our technician has completely gone through and 'Certified' this unit.
 
-
Everything was cleaned inside and out including all switches, controls and contacts including phono and tape monitor selectors.
 
-
Capacitor replaced in protection circuit.
 
-
We also resolved a decoder issue, the aligned the tuner front-end for optimum AM & FM performance as older internal tuner components have always drifted on vintage gear over the years. VERY GOOD TUNER!
 
-
The all dial & meter lamps replaced with new bulbs for trouble-free service.
 
-
We also disassembled the power switch and replaced the internal neon lamp (the power switch on this unit actually 'lights' up when the unit is off, presumably to make it easier to find in a darkened room and is off when the unit is on).
 
-
We also, removed the entire output / heat sink section, removed all the output transistors and applied fresh heat sink compound which should be good for another 30 years now.
 
-
Amplifier section had output bias and DC offset adjusted to spec levels.
 

________

-
Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 48 hours into a 4 ohm load.
 
 
 
On our test bench, this particular KR-9940, #...0541, amplifiers each produced xxxx volts  per channel for xx watts per channel @ 8 Ω via discrete output & xx volts per channel for xx watts per channel @ 4 Ω via discrete, Metal cased, TO-3 outputs.
(AC draw at idle 0.60A tested)

(Floor noise measured at 2.5mVAC)

Our technician has completely gone through and 'Certified' this unit. Everything was cleaned inside and out including all switches, controls and contacts for quiet, positive operation. We also aligned the tuner front-end for optimum performance as older tuner components have drifted over the years. Amplifier section had output bias and DC offset adjusted to spec levels. All dial, all meter, most function indicator and stereo indicator lamps replaced with new units for trouble-free service. All inputs tested, including both phonos, and both amplifiers produces clean and even sine waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine. The real, Walnut wood, veneer case oiled to near new luster. All inputs tested and both sides produce clean and even sine waves into 'brick-wall' 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! Following restoration procedures, the unit was operated continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours.
 
On our test bench, the internal amplifiers of this receiver #...2258, produced 35 volts per channel for 153 watts per channel at 8 ohms & 24.6 volts per channel for 151 watts per channel at 4 ohms via discrete, TO-3 metal cased outputs (Sanken 2x 2SC1116 & 2x 2SA747). AC Idle current at .5A, & floor noise very low @ <0.1 mVAC and DC offset adjusted tolerable spec L&R.
 
____________________________
 
 Here's another great Overseas / Military issued Kenwood's and one of the biggest ever made. The Kenwood "Eleven III". The last one of these we had lasted only a few days before it found a home with it's new owner. These are one of the most classy looking receivers out there. Photos cannot do it justice. Great brushed finish aluminum face with metal knobs to match. Full width glass window in front of an impressive array of indicators and VU meters. 
 Kenwood KR-Eleven III Features include:
 
 
-Weighted flywheel analog, 'Slide Rule' tuning
- Triple Pair Speaker Selector; A, B, or C or A+B or A+ C or Off speaker selector (two pair at a time)
 - Blazing Blue back-lit slide rule face
 - 3 band EQ featuring super quality, de-tented controls
 - Dual & selectable Power Output / Line-Level VU meters
 - Tuning and signal strength VU meters
 - FM Muting separate from the 'FM Stereo'
- Subsonic / Low Filter to eliminate excess rumble from sources such as turntables
- "Loudness" function to boost Bass and Treble in relationship to Mid frequencies at lower volume levels for a much fuller sound.

 - Built-in Dolby NR / FM decoder and it works well (brightens highs even on non-Dolby FM broadcasts)
 - 400 Hz Recording level Calibration tone
- Dual Phono / Turntable inputs w/ built-in Phone Pre-Amp- Dual tape monitors with bi-directional dubbing
 (Tape Monitors can be used with Video / CD / DVD / VCR / DAT / MP3 / iPod® / iPad® / iPhone® / iTouch® / iGadget / MP3 / XM® / SIRUS® CDR (CD recorders as well as for inserting signal processors, such as EQ's, Reverbs, Spatial Enhancers / Dynamic Processors, Noise Reduction units, Special Effects units, Time Delays, etc)
- Tape 'Two' has both standard RCA inputs as well as DIN I/O's

 - Dual 1/4", stereo headphone jacks
 - Record selector
 - Microphone input
  - Dimmer selector for light intensity
 - Timer (due to the fragility of the internal linkage on these Kenwood timers, we sell this series of receivers with their timers disconnected. We see almost a 100% failure rate on the timer linkage of Kenwood 9000's, 10000's, 11000 and Elevens. Disconnecting them eliminates the issue)
 - Pre-out / Power amp input loop
 - True "
WORLD AC POWER" 50 / 60 cycles and 110V, 120V, 220V & 240V AC current
 - 2x AC convenience outlets rated at 200 watts each

 
 
This thing is incredible. Again, we have done EXTENSIVE refurbishment / restoration work (~12+ hours) on this unit to insure it's performance, and it gets our full 'Certification'.
 Face plate, window and knobs are in perfect cosmetic condition. The real wood Walnut veneer case shows well with only minor normal wear. Edges and corners still nice looking. Just had a fresh coat of 'Howards Feed-n-Wax'. Handsome finish. Looks impressive and sounds great! This thing is incredible when lit up at night or in a dark room!! Measures 22.75" wide x 7.75" tall x 15" deep and weighs 40 lbs unpacked. Includes our standard 90 day limited warranty.

SOLD 1/11/13
SHIPPING TO CALIFORNIA

Our technician has completely gone through and 'Certified' this unit. Everything was cleaned inside and out including all switches, controls and contacts. Extensive cleaning of unit internally. Controls were 'flooded' w/ 'De-OxId' and are quiet
(very difficult to do as 'tone' section must be painstakingly removed). Switches such as the 'Function' selector and the 'Tone Bypass' switch were also flooded with cleaner. Internal fuses checked for correct value / function and replaced where necessary. World AC Power correctly set for North American current. We also aligned the tuner front-end on both AM & FM bands for optimum performance as older tuner components will have 'drifted' over the years. We also aligned the digital station display to correspond to the 'analog dial' position. Amplifier section had output bias and DC offset adjusted to spec levels. We replaced ALL, meaning '21' light bulbs, including ALL dial & meter lamps, the dial pointer lamp, 'Stereo' indicator, input / function indicators, and the timer LED with new units for trouble-free service. Intermittent tuner display, and pre-amp issues corrected that was due to a couple of 'open grounds'. Both power supply filter capacitors removed and independently tested. Other minor electrolytic capacitors tested and a couple replaced where necessary. Rerouted a poorly selected internal wire path.
All inputs tested and both sides produce clean and even sine waves into 'brick-wall' 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine, including the 'Timer'
(Normally we disconnect the 'timers' on these Kenwoods due to a nylon connector linkage sleeve that will likely break in the future (almost 100% of the time) from a user applying too much torque at some point. We avoid this likely future issue by disconnecting the linkage on all the Kenwoods that have a timer. However, on this unit, the linkage was about THREE TIMES the diameter of all the others, and strong enough to leave engaged). Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 48 hours. Total restoration time investment ~14 hours. You will not be disappointed.
   
From the original Kenwood 'Super Eleven' Owners / Service manual, "125 watts per channel minimum RMS, both channel driven at I ohms from 20 Hz to 20,000Hz with no more than 0.02% total harmonic distortion"
- However-
On our test bench, the internal amplifiers of this receiver #...0632, produced 32.5 volts per channel @ 8 ohms with 1Khz input for 132 watts and 28.3 volts per channel @ 4 ohms with 1Khz input for 200 watts via discrete, TO3, metal cased outputs. (2x Toshiba 2SB554 & 2x 2SD424)
 AC Idle current at .6A, & floor noise < 2 mVAC and DC offset <7mV.
