From my experience the - rail will need a higher current draw to become stable at -15V. Strange I know, I guess the 7815 and 7915 aren't perfectly matched (big suprise) .

Thanks, now it works!

1000R = 0.018A, 15.24V!!



The quiescent current of the OPA2134 is 4 mA. But what does quiescent exactly mean? Is it continious or peak? So do I have to keep a resistor in my PSU?

Phishead let me know when your P88 is working and what components you used.
