I am using 20-0-20 with dual independent secondaries -- this puts out a little under + and - 28V .
make sure that the LM4780 is snugged up to the heatsink --- I found that when it is properly affixed the distortion went down by about 0.03% This chip doesn't like to get real hot. (see the thread I started on heatsinking the LM4780).
