Original Description:
SANSUI AU-20000 Stereo Integrated amplifier Vintage 1977. Condition is "Used". 
I bought this integrated amp a couple years ago when my CA-3000 pre-amp needed repair.  While the CA-3000 was in the shop I used this AU-20000 integrated amp.  It works and sounds fine.The previous owner had it bolted into a rack that he custom made.  He drilled three holes in each 'ear' to mount it and he removed all the panels (top, bottom, and both sides) to "let it breathe." ... When I purchased it he put all the panels back on but he couldn't find all the original screws for the panels so I'm sure there are some odd sized panel screws here and there.  I also filled in the three holes in each ear with black silicone.  see pictures.  Sitting on my stereo shelf, one doesn't notice where the holes were unless you point them out or if you do a close inspection. Signs of use but everything works.  I used mostly the tuner and aux inputs.  I have my CA-3000 back from the shop so I no longer need this amp.
