[sdiy] Power Supply Trouble

[Scott]

Anyone know if schematics are around for Power One supplies? 
thanks for the advice so far.  I should have time to pull the supply out today and start testing.  (its always a tough decision..  to play the synth, or to work on the synth)

First thing I'd check would be the input voltage to the regulators.
