Hi,

I have some spare PSUs built for my Miro's PCM63 DAC. Schematic and layout attached.
2 independend sections (separate grounds), transformers for +/-5V or +/-12V outputs, 230V input. Tell me what voltages you need, I'll solder the transformers.
LDOs 7A4701/7A3301, pots for fine adjustment. Caps - Nichicon KZH. I am quite happy with them, no hum and very good PSRR. PCM63 DAC measurements:

Did couple of measurements today, PCM63 DAC at 0dB:

-100dB @ 50Hz, I think is a decent result for DAC on a cardboard 🙂
