The green wire should go to the chassis of the amp.  It does not connect 
to the variac (unless the variac is in a box which you could ground 
too).  The black and white wires go across the whole variac coil.  The 
two non-ground wires to the amp go to one side of the variac coil and 
the movable tap.
