Building onboard power supply

[EmilEnglin]

Hi,
I just got a d8b without the CPU/power supply. The plan is to use it as a daw controller with d8bridge, so I will need to build an internal or external power supply for it. Does anyone here know the specs on the transformers that are feeding the board? I've found some schematics so I know the voltages, and that it's both smps and linear transformers, but I don't know the recommended current specs.

If anyone here have done this and got the time to share some knowledge about this, it would be great!

Thanks.
Emil
