Can someone date this power trans for me please?

Here's the pic:


Just looking for a date for it. I *think* the 682 makes it an Electrical Windings trans. If it does though, doesn't that date to a '93? (first digit on 2nd line is a "6", I believe)
Help

Edit: I'm an idiot - it's the output trans, not power trans. Don't know what I was thinking...

More likely the 34th week of either '69, '79 or '89. With a date code like that, you have to guess the decade.
