Sansui AU-7500: Introduction
I found this little gem in the local flea market. This was a lucky day.
When I plugged the AU-7500 amplifier and played a few audio tracks, I instantly recognized the authoritative sound of the AU-x500 series filling the room.
This will be a long process but I document it well. Maybe you find my work inspiring or helpful. Or my descendants, during a distant future maintenance, should this amplifier survive the years to come...
