1kW+ Class-D Amplifier, Pt1 - October 2023 - Silicon Chip Online
This mighty monoblock amplifier uses a prebuilt module and some relatively inexpensive switchmode supplies to deliver well over 1kW into 2Ω loads and substantial power into 3-8Ω loads. It can be built for around $1000 (that’s more than 1W per dollar) and fits into a metal toolbox, so it’s even portable! by Allan Linton-Smith
