Oops, I for some reason I got it in to my head that you have 630, not a 640. None the less the front end of the 640/620 look the same.
Yes, looks to me like the push pull does give you an extra connection. Maybe this is too simple of a way of looking at it, but if you were to eliminate the bottom half of the output transformer it looks like the 620/630.

Can't think of anything witty.
