I don't think there is anything wrong with your browsers as I think this is one small portion of the website that is not completed, so there may not be any photos of the back of the unit. I can tell you that it basically looks like the back of an SL preamp, with a set (2 duals) of speaker binding posts about midway on the unit, arranged vertically. There is also a switch located on the back to kill amplifier output for headphone listening.
I believe that the power output is the same as the 170. For those looking for AVA quality in an all in one unit, this is a nice piece.
