Re: Re: Balanced F4
Got it thanks.
Refering to this diagram: http://www.diyaudio.com/forums/attachment.php?s=&postid=1672598&stamp=1228160049 it is bridged configuration with two amp boards per channel providing more power as described here (page 7): http://www.firstwatt.com/downloads/f4_om.pdf
Each PS board in that diagram represent single voltage supply (+ or - ), so for symmetrical supply required by F4 amp you need two of those, connected to each amp board.
You can also use 4 of those PS boards (it's a PS board broken in half at scoring line), 2 per each amp board.
Got it thanks.

why not connect single PS pcb with single pair pcb instead of connecting both + and - to different pair pcbs
