It's McIntosh. It's tube. It's beautiful. Need we say more? The MR71 is well-regarded as one of the best FM tuners McIntosh ever produced. Even though we acquired this particular example in pristine condition, we still put it through our complete battery of tests, and we found no major issues. We naturally replaced the selenium rectifier with a modern diode. We also swapped the OEM lamps for LEDs, and replaced all worn caps. The alignment was spot-on, and you can expect this piece to perform at spec.

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.
