siplelist class d diy amp?

[kaukasion]

any schematics or comments?

i want to build something simple that i can just keep modifying for more power

i want it to be class d
so i dont have to spend a fortune of money/time/space on a heatsink
i have a few decent sized ones laying around

i wanted to build it to power a subwoofer cabinet im planning on building

it needs to be monoblock capable 1k

so who wants to help the new guy
cause i wanna learn 😀

Two I have seen:

Circlotron's work:

and the National chipset:

I think a neat amp would be if somebody takes the National chips and does a "minimizing" on them, since the datasheet schematic is an unrefined testing application with literally dozens of bypass capacitors, but I have not seen that yet.
