Schematic taken from Nelson Pass „First Watt“ Website. Parts designation same as used in the description from the pdf. A few modifications by me, and a "all in one Design" (Amplifiers, rectifiers, fuses, capacitors one the PCB) .
Each power rail got 94.000µF, a stereo amp have all together 376.000µF.

600VA Toroidal transformer with 4 windings, for separate supply of the power amplifier modules. Separate pcb with dc block + filter + inrush limiter
