I built a power supply similar to this using two lm338 regulators. When I run just the PS, I get the correct voltages relative to ground, but when I attach my audiosector lm4780 board (parallel config) the voltages of +rail, ground, and -rail get skewed by 14 or so. If i connect the circuit common ground to the chassis i get blown fuses.
Does this sounds like a familiar problem to anyone? I have check my circuits over many times and everything seems correct. Any ideas?
