For this kind of voltage it does not technically matter. Green on both to visually match (?)

board is op and running
have now run for more hours....drift about 0.3vdc down from 15vdc

i have no resistor to load the supply with ..so i test it without

R1 is 2 ohm

cooling is good ..easily holding on the heatsink---

will the dc voltage go up when i mount my load ??

so close to testing on my Mirand dac

It could show little less drift due to less heat from M2 because of power sharing with the load but not much. That drift is its normal thermal settling before going steady in this voltage area. Better allow for it in set up anyway.

some problem with connection

i shall use 15+ 0 -15

when i mount the 2 0 volt together the regulator goes out on the led on positive and negative board

works fine without the 2 0 volt mounted together

is there something in the wiring i have done wrong ?

If they got a common sink check the Mosfets insulation
