What else to know about the McIntosh MR 73?

The McIntosh MR 73 is a precision engineered, highly sensitive solid state AM/FM tuner. The research staff of McIntosh Laboratory, using the latest technology in solid state physics, has developed many circuit advances including: Phase linear crystal shaped IF amplifiers. Integrated Circuits that are the equivalent of 16 transistors, 3 zener diodes, 5 diodes and 23 resistors. Special multiplex (stereo) detecting circuits that eliminate critical adjustments. Ultrasonic muting for complete silence between stations while tuning. Automatic stereo-mono switching that is "clickless" and completely electronic. Visual multipath indicator to help avoid multipath distortion showing as a visual indicator of correct antenna direction for minimum multipath reception. New D'Aarsonval movement meters of increased sensitivity which do not need zero setting adjustments. A new computer designed filter to reduce noise from stations broadcasting subcarrier auxiliary music services. No other tuner uses such a filter. \- Sterenomono
