The McIntosh MR7083 is a solid-state AM/FM stereo tuner, manufactured from 1990 to 1995. It's known for its advanced tuner design and features aimed at high-quality radio reception.

Functional Notes: The attached video demonstrates all functions working as expected, with the exception of the AM reception, which is noticeably weaker than the FM or other AM tuners tested in the same location. Please watch the video for full details. If you're interested, feel free to ask any questions or make an offer you're comfortable with.

Cosmetic Description: The exteriors are in very good condition for their age, showing typical signs of use such as minor cuts, scuffs, and dust. However, the front face glass has a noticeable mark where the back film has detached, along with some bubbles. Please examine the images closely, as they may reveal other minor cosmetic imperfections not specifically mentioned.
