Sansui - AU-20000 - 100V Solid state integrated amplifier

This unit is in excellent condition and works properly, and has been fully restored by our specialist technician. Most of the electrolytic capacitors across all boards have been replaced (selected positions upgraded to film/ceramic for sound quality); the power meter IC has been replaced to correct meters deflecting without a signal; the AC power cable has been replaced; all switches and the main volume, and the relays and all terminals, have been disassembled, polished, and cleaned; the circuit boards have been cleaned with the solder inspected and reinforced; the output stage transistors have been re-treated with thermal grease; and the panels and knobs have been cleaned. Finally, the idling and DC offset were adjusted, and the unit was measured and listening-tested for approximately 14 hours to confirm correct operation. A service record is included.
