Value drivers

  • Early Sansui look and warm presentation
  • Clean black faceplate and wood case
  • Recap and noisy transistor replacement

Common issues and restoration notes

  • Noisy small-signal transistors
  • Oxidized controls
  • Worn case veneer

For Sansui AU-999, buyers usually discount undocumented service because noisy small-signal transistors can change repair cost quickly. Keep receipts, note replaced lamps or capacitors, and photograph serial plates, controls, faceplate edges, and included accessories before listing.
