Hello dear Diy Family, I'm building power supply fro mic pre. I'm using schematic from JLM Power Plunt. On Phantom power LM317 input I'm getting 81 V, why? I have beautiful +24V rail good and on phantom power regulator i have 80V on input, I'm pretty sure i did all the components right, is there a mistake somewhere in schematics? Cause on diodes D1 and D3 it's 82V how come?
here is a schematics:
