Racking Cadac modules, adding OT, but which one?

[API]

I am racking up some pairs of Cadac modules and since they are unbalanced out in the desks i wanted to add an OT for balanced line out.
Looking at the schem they seems to be +4 at the output so something like a 600:600 maybe?

Also, looking at the postfader amp, do you think there is enough juice in the amp to drive a transformer without any problems?

Thanks.

No ideas??

600:600 may be fine.

Smaller image (6616px?) might also be fine.

;D Sorry about that, did not realize it was so big.

Will try the 600:600 and look on my scope.
