nice job Marc, one minor thing, R19, R18 pads are right over the mosfet pins. if one leaves the cut pins too long, it might short with mosfet pin. although chances of this happening is very minimal.

Very nice board. Does double die Allfet allow higher rail voltage and more power output?
More current for sure......Lazy Cat use them in his first one. Holton use them in his HPA-NXV200L R4.1 module :
I want to use them instead of 2 single die per rail..

Replace 56R with 33R and 4k7 with 2k2, balance pot can be single but dual have better mehanical connect with pcb.
Regards
the double die devices are rated as 250W
That using my standard model gives a maximum output power of 125W
Sum Pmax = 250+250 = 500
Max output power for mosFET stage = 500/4 = 125W
that could be into 16ohms or into 8ohms or into 4ohms or into 2ohms.
You select the Supply rail voltage to give whichever output YOU require.
So one could build an array of these for an analog input selector with no hard contacts in signal path? Cool.
Yes connect outputs in parallel and you have audio selector, you can use pot selector to drive this switchers instead relays.
This is drive circuit... 120k is from audio switch.
