Hi Edward,

My experience with old electronics is that capacitors deteriorate with age. Look for bulges on the top and leaking brown  goo.  I fixed a NAD amplifier and a Technics turntable by doing this.

Here is a link for the service manual for your receiver which should help:

HiFi Engine is a very good site for old electronics.  You may already know this but it may help others reading this.
