Odyssey 500 by Magnavox (vintage game machine)

I am looking for specs on the Odyssey 500 game machine by Magnavox.  Years ago, I had searched the web high and low, to no avail.  I am wondering what voltage is required (A/C. I believe!), and what channel to put the machien on.

This two-player, quality game machine has six paddle sticks, three for each player, and has selectors to mash up three games with three game boards with three game types: tennis, pong, hockey.  It plugs into the wall and TV.

Here's a picture of the Odyssey 500 game machine:
