McIntosh MR7083 AM/FM Tuner

Great sounding solid state tuner from McIntosh, and a perfect match if you've got other Mc gear from the 1980's or 1990's.

Super clean and working perfectly. We were able to pull far away stations from our shop with ease.

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.
