Standard F4 Schematic 4ea of the .47Ω in parallel.
So, .12Ω or so.

I'm now became curious, so I measure supply voltages of my J2:
(Because my four channel F4 now not available.)
So:
Trafo secondaries are 18,45VAC (It has four independent secondaries, all of them goes to a similar 35A bridges, and it followed by the four cap banks.)
At the rectifiers DC side I measure 22.8VDC.
22.5VDC passes to the amp board. Plus and minus of course.

So I think its similar to yours.

Nope, This thing is just WONDERFUL.
I just upped the bias from 300 to 350mV just for kicks.
My highest middle pin temp is only 51C, my fans are doing a fantastic job keeping this thing cool.
I have finally gotten a hold of some 14V Zeners to run each pair of fans from, they are inaudible from 3ft. away.
