McIntosh MR77 Vintage FM Tuner in Wood Cabinet - WOW
If you haven't heard a vintage FM tuner recently, you really owe it to yourself to give one a listen. The right model matched with the proper antenna will make some of the warmest and most natural sounding music you've (ever) heard. Especially through an all analog piece like this McIntosh MR77.
We are very lucky in our area to have some of the best sounding stations in the world, and you better believe we take full advantage. If you come to our shop you're likely to hear our local Jazz station WBGO playing from one of our vintage tuners just like this one.
Sitting just below the renowned McIntosh MR78, this MR77 model provides 99% of the sound quality with a just a few removed features, which most users would never ever use or miss.
My favorite feature (that's actually not found in the MR78!) is the "magic eye" indicator. It's an actual tube-based light emitting component with two lines that fluctuate indicating multipath reception. Super Cool!
Condition is very good with only the slightest peeling on the glass faceplate. The cabinet is very presentable for its age and looks amazing when matched with this tuner.
Thoroughly tested in our lab utilizing our Sencore SG80 FM Generator, which allows us to generate a reference FM signal of any frequency and amplitude, and then measure the results of the MR77 tuner output on our Sencore PR81 or oscilloscope. This unit passed with flying colors and produced a natural and warm sounding output.
Includes the tuner, wood cabinet, and manual (not pictured).
