Look again, it is a regulator (feedback). T101/T102/R107 is a CCS for the resisor network R108 to R111, ...
Isn't your CCS based on the supply voltage / R105+R106?

Well, maybe not so much.
🙂
If the Vbe of T101 is operating in the flat slope then the effect of supply voltage on the CCS operating point will be very small.
OK, not as bad as I had originally thought.
I still would not do it that way though.

But you still prefer the zener reference?
LOL
Yes...on paper I prefer it.
But I have not tried it yet.
Time will tell.
Actually, if you would have used the output to source the CCS I would probably have accepted it.
How is the step response for 10% to 90% of load? (and 90% to 10% of load)
I use this as a stability indicator.
