McIntosh MR7083 Tuner - Slim Version - NEW GLASS!
479 South Broad Street
Glen Rock NJ 07452
This is a fantastic sounding modern "almost vintage" solid state tuner from McIntosh, and a perfect match if you've got other Mc gear from the 1990's or earlier.
McIntosh made two versions of the MR7083, narrow and wide/modern, as this model was produced right on the cusp of McIntosh expanding the width of all their components in 1992.
Meaning this MR7083 will match the look of your early 1990's and earlier gear best. If you need the later "wider" version we have one currently listed for sale here.
I routinely take our tuners to my home lab for testing as we enjoy some of the best FM in this area being so close to NYC. It's always interesting to see how tuners differ in functionality, speed, and overall sound quality.
First I don't think I've ever had the pleasure of using another tuner that searches and finds the next station so quickly. Quickly meaning it finds the station, locks in FM/FM stereo, and sweet sounding FM is played near instantly.
Presets, and really every front control of this tuner is also super fast and a joy to use. When I brought this back to test a newly restored MR80 (listing soon!) I was actually hesitant to give it up.
Plus MR7083's we test seem to pull in stations that no other tuner has found, except for the groundbreaking MR78/MR77's.
Overall FM sound quality is stellar. The local Jazz stations and modern R&B sound so wide, musical, and just sweet. Not the FM I remember growing up that's for sure, but then again my tuner didn't cost as much as my car like this did!
Even AM sounds great which is really saying something. I routinely listen to the legendary 1010WINS Newsradio in the morning before heading into the shop.
This MR7083 is super clean and working perfectly, and will ship to you in an official McIntosh shipping carton.
SkyFi Cosmetic Notes:
• Brand new McIntosh factory front glass faceplate installed, along with new lamps.
• AM Antenna ground connection button is missing. The external AM antenna input can still easily be used by connecting the ground of the antenna behind one of the rear chassis screws.
• Slim faceplate version of the MR7083 at 16-1/8" Wide (vs 17-1/2" in later units)
SkyFi Service Notes:
• Tuning control lubricated for super smooth action.
• Adjustments checked to ensure proper dial tracking and stereo separation.
SkyFi Notes from our Lab and Long-Term Listening Tests:
• All station preset functions tested and working normally.
• FM Stereo locks in fast even with weaker signals where other tuners would fail.
• Dial Tracking near perfection if not perfection. Joy to spin and use.
• AM tested and working as it should. 1010WINS never sounded so modern.

More from McIntosh:
The Mclntosh MR 7083 is a high quality AM/FM Tuner whose design has been governed by insistence on high performance with long life, great flexibility and sensitivity.
Mclntosh has earned world renown for its technological contributions for improved sound. When you bought Mclntosh, you bought not only high technology, you bought technological integrity proven by time. The Mclntosh MR 7083 Tuner is continuing evidence of Mclntosh technological superiority and integrity.
Your Mclntosh MR 7083, above all others, will deliver the best sound and the greatest ease of use with a high degree of flexibility.
Some of the features that set the MR 7083 apart from the ordinary are:
The advanced AM/FM tuner design of the MR 7083 displays the station frequencies digitally. Stations are selected easily in any one of these ways: A. use the manual tuning knob, B. use the SCAN up or down touchbuttons, C. use the preset station touchbuttons or, D. use the SEARCH which will preview the preset stations for 5 seconds each.
The sound enhancing SPATIAL audio processor provides an aural picture that is more "stereo like" in quality and dimension. On noisy, weak FM stations or AM stations, SPATIAL provides reduced noise and retains a broad stereo-like sound.
High quality tape recordings of FM broadcasts can be made without the interference that stereo trans- missions can cause. Carefully designed suppression circuits eliminate the potential for stereo carrier noise when making "off the air" tape recordings.
A unique Phase Locked Loop Multiplex decoder delivers STEREO FM with lower distortion, lower noise, and better separation.
The most useful and flexible AM antenna system will suit your particular installation. A low-impedance loopstick will, in most local areas, provide AM signals while rejecting noise and interference. In noisy AM locations, an external noise reducing, noise canceling, shielded loop will provide ideal input signal. In a remote location, a conventional 'long wire' antenna can be used.
The SkyFi Testing Process for Tuners:
We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR. Vintage analog tuners also have moving parts related to the tuning gang and dial string. These parts are inspected for smooth operation.
If the unit passes visual inspection it is bench tested for a handful of key performance parameters using a Sencore SG80 AM/FM Stereo Analyzer. The SG80 allows us to “simulate” an ideal radio station using precision test signals instead of music. This device, in conjunction with an oscilloscope allows us to properly evaluate the following parameters:
1. AM Reception (Where Applicable)
2. FM Mono Reception & Tuning Meter Function
3. FM MPX Reception (Stereo)
4. Dial Tracking - How accurately the tuner dial or display indicates the actual frequency of the broadcast being received.
5. Stereo Separation - A properly working stereo tuner will have minimal crosstalk between the left and right channel.
6. Sensitivity & Signal Strength Meter Function - By lowering the output of the SG80 we can simulate weak stations and determine how well the tuner will be able to pull in weak distant stations. This adjustment also helps us verify signal strength meter function.
If the tuner has acceptable performance related to the parameters above we connect the unit for listening tests with a simple dipole antenna. We listen for audio reproduction quality of local stations and evaluate how many stations the tuner can receive while we sweep through the dial. We are looking to verify that the tuner can decode stereo on strong local broadcasts and pick up a wide variety of local stations at the bottom, middle, and top of the frequency band. At this point we also test convenience features such as muting, filters, built in oscilloscope function, etc.
We finish up with an extended listening test on our long term test rig. We tune in a strong local station and monitor for drift over a 2-3 hour period.
