If I want to change the output voltage to 30V, i must change the R10 value to 6.81KΩ, use default D5 zener diode BZX55C12 (12V) and e.g. an Avel Lindberg 30VA 15+ 15V toroidal?
Is 30V enough or should I go for 36V (change the R10 value to 4.99KΩ, use default D5 zener diode BZX55C12 (12V) and e.g. an Avel Lindberg 30VA 16+ 16V toroidal)?
I could use default components/values on the entire board except for the opamps, and instead using e.g. the Texas Instruments THS4631D with a maximum supply voltage (VS Supply voltage, VS– to VS+) of 33 V?
By the way, all the links to datasheets for the Analog Devices opamps are dead. And so is the link to the Linear Techonology opamp.

Regarding opamps I "simply" need to find one that can handle 36V or more (so for example the THS4631D will *not* work when going for 36V, correct)?
Ok about the dead links. Just thought you'd might like to know. In case you want to update the links for the Analog Devices opamps here are the new links

Also, there is no need to upgrade the heatsinks?
No, just make sure the case is ventilated.I have some difficulties understanding the opamp datasheets. Maybe you could educate me a little and tell me which parameters/specifications to look for? For the AD8065 for example I see a supply voltage range of 5 V to 24 V but no maximum indication. Help plz.
