This is a SANSUI AU-555 integrated amplifier.

Power has been confirmed, but operation has not been verified, so it is listed as a junk item.

An envelope containing a circuit diagram is attached to the bottom.

There are marks from the rubber feet of other equipment on the top panel, and 5 knob decorations (thin black plastic plates) are missing, so I'm offering it at a low price.

The knob decorations can probably be replaced with round stickers sold at 100-yen stores.

This is the top model, Sansui AU-α907DR.
Although the power turns on, the protector indicator is blinking, making it impossible to confirm operation, so it is being sold as a junk item. No manual included.
There is paint peeling on the lower right side of the cosmetic plate and at the back. It has been stored inside an audio rack for over 30 years, so it is in relatively good condition.
No claims, no returns please.
Since it weighs over 32 kilograms, shipping may take a little longer.
It may be wrapped in bubble wrap and shipped in a cardboard box or recycled cardboard box.

Power-on confirmed.
I have confirmed that sound comes out when connecting a record player and speakers, but the individual switches do not function.
The volume dial also seems to spin freely and cannot be adjusted.
In addition, one side of the karaoke button is pushed in and does not return.

As this is an old item, there may be other malfunctions.
Please understand this before purchasing.

Normally, electrolytic capacitors deteriorate after 30 years, but there is almost no attenuation, proving its low usage frequency.

Operationally, it has been maintained by an audio specialist.
The maintenance includes strengthening cracked solder, cleaning and repairing switch and volume contacts, cleaning the exterior, and circuit checking with an oscilloscope and tester.
The sound output is balanced between left and right channels, with no distortion or scratchy noises.
It produces a soft and expansive sound, as expected from a high-end Sansui unit.
