Sansui AU-9500 - Fully Restored

Sansui AU-9500 vintage integrated amplifier for sale. This is in excellent condition and has been fully restored. Sounds absolutely amazing with the classic Sansui sonic character; powerful, rich, musical tube-like sound.

Extensive restoration includes; power supply and amp boards completely rebuilt with nearly every transistor replaced, all capacitors and all solder connections reworked, all bias pots replaced, all switches and pots cleaned, all connectors scrubbed and cleaned, all diodes replaced, power indicator lamp replaced with new LED, amplifier bias set to factory specs, power cord cleaned and prongs cleaned and polished, tested and confirmed for a return to its former glory!

The AU-9500 was the last integrated amplifier overseen by Sansui's founder, Kosaku Kikuchi, before his retirement, often regarded as his personal masterpiece. This was his swan song creation.
