I may circle back to the power supply after fixing other issues with the set. The trick is finding a DC power source "clean" enough to not inject problems of its own.

If you are trying to borrow power from the set I highly recommend using a LM317 family linear regulator to drop some voltage...It will make the supply much cleaner with reasonable filtering on both sides of the reg.
