To reanimate this thread, I also have a few questions about PR regulated PSU.
First of all, what replacements could I use for the J309, they are hard to get here? Is J310 identical as I can read from the datasheet?
Also, what values did you use for resistors R1, R2, and is there a point in trying with a higher voltage - say 33V or 36V to squeeze a bit more from the chips?
