NAD model 4150 AM/FM solid state receiver.
This unit took a hit to the rear and probably exasperated latent factory created problems and became intermittent. Even though I am not set up for Solid State, I will try to "repair" just about anything once. You never know if it is something simple like a cold solder joint on some hot component lead needing only a touched up.
This is not a restoration but only a "Fix or Repair". I could not locate any readily available schematic or alignment date. No alignments were performed.
The case has been cleaned of dirt and shined up with some Glayzit.
Even today some solid state electronics is collected and appreciated as vintage gear. The best example (for me) are NIXIE tube displays. Picture from; http://en.wikipedia.org/wiki/Nixie_tube
