Thanks Kevin.
I'll stick with the output transformer that I have for now.
As for the input transformer, of the two suggested connections on the 1540 data sheet is any one better suited than the other for this circuit?
I think I read your response on another forum to not use the 12k loading resistors?
Thanks again for your help with all this - much appreciated.
Thanks!

Follow Ups:
If the source is balanced, you should use the left schematic. The RC network can be deleted for a 600ohmish source impedance.
For a single ended drive source use the right schematic in the data sheet. You do need the 12K resistors in this case.

Thanks Kevin. 600ohm source is what I'm going for.
