When it comes to vintage Mac tuners, the MR71 is on every collector's short list. This is such a nice example, with pristine glass, and beautiful chrome chassis without the hint of pitting. We've gone through it from top to bottom, and didn't find much that needed attention, so while we were under the hood, we upgraded the lamps to LED. What's not to love?

- Liner Notes
The Mclntosh MR 71 is a precision-engineered, highly sensitive FM Multiplex Tuner.The research staff of Mclntosh Laboratory has developed five new tuner circuit improvements for the MR 71.1. Automatic stereo-mono switching that is "clickless" and completely electronic.2. Multipath indicator to eliminate multi-path reception by showing when your antenna is rotated to the correct position for minimum multipath distortion.3. Double-tuned input circuits before the first R.F. amplifier to reduce spurious responses.4. New D'Arsonval movement meters of increased sensitivity which do not need zerosetting adjustments.5. A new computer designed filter to reduce noise from stations broadcasting sub-carrier auxiliary music services. No other tuner uses such a filter.
