One of my favorites from back then is the Mission 776/777 combo. No detail by modern standards but punchy as Cassius Clay (time appropriate). Combined with Altecs or Klipsch horns, it could hurt you. Ahead of it's time in many ways. First battery powered preamp.
There were some rare Yamahas and Kenwoods that broke through the consumer electronics barrier but beware of obsolete FETs.
