I was very active in hi-fi during that era. The build and sound quality of receivers peaked in the mid- to late-'70s. The '80s saw the introduction of cheaper metal work, and integrated circuit output stages became more common, as did the now unobtainable LSIs used for digital control and tuning. The worst of all this began in the mid-'80s when manufacturers began cheapening the power supplies. I can't even count the number of customers who complained about the lack of bass and dynamics compared to their previous gear from the '70s. Specifications continued to indicate adequate performance, but transformers and capacitors were smaller, and the difference was clearly audible. One of the best lines from that later era (and one of the last to maintain excellent sound quality) was the Harman Kardon series of "high current" receivers and amplifiers.
The biggest problem with any gear this old is the need for restoration. Owners also sometimes run into a wall when it comes to worn out controls and switches, most of which are no longer available. This era is way over-priced on the used market, and I wouldn't have most of it. My suggestion would be to buy a vintage power amp and rebuild the power supply. Then add a modern preamp, tuner and phono stage. This will provide a high quality system that works well.
