It works like a charm.... The higher the secondary voltages, the lower the losses, all things being equal. I've built them with 24,28, 36 and 48v secondaries, with tha quality depending on the construrction more than the specific secondary voltage. Please don't use a typical(one with no shield between primary and secondary) toriod transformer. A simle split-bobbin (like the RatShaques) EI core transformer minimizes capacitive coupling (of noise) by simply physically separating the primary and secondary, hence the 'split'.
The major advantage of lower voltage secondaries is that you can use caps accross the secondaries that would be practical for full mains voltage.
