The AL-80B transformer is in that voltage range, and has nearly the 
same secondary resistance as your transformer. It sounds like you 
have about the same thing performance, if the other losses 
are also the same.

Expect about 10% or more voltage sag no load to full load if you use 
enough capacitance and keep the current down around 400 mA or so. 
About 20% or more sag if you try to pull 800-900 mA.
