R7 or R9. Q1 is a CCS that uses the emitter resistance to set the current. That current is pulled across the string R9-R5-R6. So you can change the current slightly or change the string resistance. it looks like R9 could be specified as a potentiometer anyway, which will give you some adjustability.

If your French is fluent enough for few technical bla bla, you may look at that:
Rgulateur Alimentation Haute Tension
If not, pictures may help anyway.
