Yes but for the price of one of those low end surround receiver you can 
get a great pre-1985 amp that will have a real power supply with real 
spec. Would you say that the Pioneer SX-A6-J is a "low" end at a retail 
of 800$? At that price I can get an incredible piece of Vintage 
Amp/Preamp/(Cd Player or Turntable).
