Default HV Regulator

Just wanted to get some inputs on this circuit. If I wanted 500-510v instead of 485v, what value(s) should I be changing.

Thanks
Ray

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.

Hi !

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.
