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.
