i had a DE power supply( jurassic park) with very low 5 volts. Ac input was correct, caps were not the problem. looking at the datasheet, the LM723 requires 12V at one of the pins. the 12 v was missing. DE ran the ac input thru some diodes and resistors on the board. rather than go thru it, i pulled 12v from the power supply's 12v bridge rectifier for the lm723 input and have a rock steady 5 v. just make sure you cut the trace feeding the lm723. been working for yrs.
