I am not the original owner. Units were working perfectly as of June 14, 2019, when they were replaced with a new Sanders 500 watt/channel stereo amp.
The appearance of the units is good (7/10). There is no discoloration of cooling fins. Visible marks: On the top of one unit, “Right” has been scratched in small letters beneath the “PASS LABS ALEPH 2” logo (see photo). On the top of the same unit, there are two small scratches (< ½ in.) in the lower right corner (see photo). On the top of the other unit, “Left” has been scratched in small letters above the “PASS LABS ALEPH 2” logo (see photo). The marks described here can only be seen by close observation.
Comes with AC power cords, but no boxes or containers are available. The Owner's Manual is available as a PDF file from Pass Labs: https://www.passlabs.com/sites/default/files/a2man.pdf
