Aleph 2 build questions

[Narside]

I'm about to use the power supply from PS-X2 (please see the attachment). The question is whether it is ok to use single power supply for 2 channels of Aleph 3 (8 ohms load) or each channel must be powered by individual power supply? so that means i have to build 2 Power supplies?

You can use a single psu, but a 300VA transformer may be a bit small if you use 20V rather than the original 18V secondaries.
