Just a suggestion: you're sure there no ground
reference problem on pin 7 (V-) of the 723? (hence raising the Vref).
I've seen small 723-based supplies with sense leads where the 723 V- is on the neg.
sense lead rather than neg. output lead.
I checked it, and don't see any offset from ground elsewhere in the circuit.
This particular supply rail doesn't use remote sense. They only use it
on the 5V 30A supply, which is on a different board.
