Someone have the correct Mouser/Digikey BOM?

I think that will depend on the board layout Peter comes up with.
This amp puts out 2amps or 100W a channel, and the 1 ohm resistors also really belt out heat.

I think a thick film resistors attached to the heatsink replacing these would save space and keep from melting the boards.:D

C4 needs to be large enough to avoid turn on thud, bad for FR speakers... I use 33,000uf

We know what the power supply looks like, it uses 4 X 1 ohms vs 4 X .47 ohms like the F3-F5, and Peter already has those around to view.

Here is the board layout I used, stolen from other thread.

I have a question for you Daniel. Are you going to increase the room for capacitor "C2" so that larger film caps can be used to bypass the 15KuF output capacitors? I have some 1uF 200v "Vitamin Q" capacitors that are just begging to be included in this amp.
