Power supply circuits

Heath	Power supply circuits okay here's another ignorant question. Although if I weren't ignorant, why would I ask? Looking in my Hammond catalog I see a power transformer that puts out 350-0-350 AC volts RMS. If this is the case and I use a choke filtered full-wave bridge rectifier, their equation shows that my peak and average output in volts D.C. will be .9 times the secondary volts A.C. I am assuming that in this case I will get 700 volts from a full-wave circuit and 350 volts from a half wave circuit so my output will be 630 volts D.C. but since I'm still learning and I have no good reference to check I'm asking one of those with more knowledge than myself. Am I right?
