Yes, for any decent transformer it's not normally a problem - my comment 
was meant as a caution against taking it for granted. I've seen it where 
a transformer (not a choke input type) was marginal for the load so 
voltage was sagging and someone thought they would add lots more C to 
try and prop it up.

As you say, PSUD is your friend.
