Cesar,

I think you have the transformer footprint figured out correctly. 

Sounds like you have resolved the PTT issue, and have moved on to 
the area of the board where the IRF510's blew as per your first post.
Perhaps T11 did get damaged somehow when the IRF510's blew.
But I'd think more likely it was either L8 or L9 that got damaged, and/or the associated traces.
