Onkyo TX 4500 MKII Stereo Receiver - 1977 - The first stereo receiver with quartz-synchronization for the FM band. Even the previous TX-4500 was a successful ONKYO upper middle class. Here the design has been optimized. For the display scale real thick glass is used. An expression of timeless elegance, in my opinion. A heavy receiver with high power for 3 pairs of speakers. 65 watt per channel.
