Post YAC514-F DAC "cut off"

Well, I read a lot about digital & analog +5 PS & if I know the "consumer" with datasheet then it's more ore less clear. My question is about YAC514-F DAC on which any info is absent.
So here we go: in original circuit (Yamaha CDX993) PS +5 v is made on M5290P (tracking + - 5 v regulator from Mitsubishi) + power trans. 2SB1565 + Panasonic Pureism 6800mF before & 480 Elna Silmic after regulator. I'm already "cut off" the servo from this rails with it's own trasformer & now it's the DAC's turn. BUT it has 6 (!!!) power pins and I dont know which is which. How to organise power supply to this pins: one main + 78L05 on each + BG HQ Nx or just one main or just six 78L05 after diode bridge?

Thank you,
