I am looking for the photos of my AU-111, so far I only have a shot of the interior when I was working on it and a photo of the speaker terminal I made to replace the original.
According to the serial number this Sansui Au-111 was manufactured in 1966. It is the version with two-tone black and silver knobs and 2 bias pots. One large knob and the silver top of a small knob are missing from the original set. I replaced all knobs with black anodized aluminum knobs that I thought matched the black anodized face plate. When I purchased the amp there was no bottom plate and no tubes. I made a bottom plate of perforated steel and, like the original, used rear casters. The front feet are made from Az. Iron Wood. All electrolytic capacitors, except for 3 in the phono section, have been replaced. The power cord was not original and was replaced with an IEC jack. As there was no safety ground to chassis on the original I did not connect the ground to chassis.
I had trouble connecting speaker wires to the screw type speaker terminals so I manufactured a plate out of lexan, the same size as the original, but used terminals that would accept banana plugs.
I enjoyed this amp but it isn’t the holy grail. Maybe because I had heard such praise for the Sansui AU-111 my expectations were to high. I had a new Jungson JA-88D at the same time and would have been happy with either in my system. In fact I sold the AU-111 and kept the Jungson.
