On mine,  it's on the main case, left corner between side and bottom,
between the left output flange and front of case.  As you read the letters
and numbers, the two-letter code will be first, i.e., on the left.  There
is a rib through the middle of the code, so be sure to clean off enough of
the case to find it, say 2" by 3" or 4".
