I tried it with a beefy diode between the pass transistor and the feedback resistors, and it works OK. Haven't checked for noise and stability - too busy checking the two current limiters, and trying to chase down a strange fault (may be due to a failing o/a), but looking quiet and stable. Bit of voltage sag under load but that may be due to something else.
Here's the complete psu schematic - I've only built channel A for testing so far. Have tested the voltage tracking with a battery, need both channels built to test the current tracking.
