[hpsdr] Power Supply test

[Bob Fish]

Hi Guys,
I am a pretty good builder, but not much of an engineer I'm afraid. How 
about sharing the schematic of the power supply you built. I suppose 
there is a transformer and some diodes or a rectifier, some filter caps. 
Three or four regulators, one each for the supply voltages. But which 
ones and the layout of the thing are the difficult part for us non 
experienced designers.

Thanks in advance,
