Depends on how low in frequency you want to pass through the modulation 
transformer, Mark,
and how much current you'll be running in the final section of the rig.

Typically, 8HY per 1000 ohms of impedance load in the final is a pretty 
good rule of thumb.

8~10uF of coupling should do nicely.  Depending on where you put the 
coupling, will determine
how much of a voltage rating the capacitor needs to be.
