Yes let's do this speaker AMP.

The stm32 I have that has DAC stm32l476 disco

I have that one too. I thought it has only mono output?

Just checked, the one on my table is the 407discovery.

What I made a schematic and PCB for this circuit last time. The resistors were cheap China 25w resistors. But it's in Proteus.

Have a pdf copy of the schematics?

Will recommend KiCAD for hobby project since it’s open source and works well too

Hi guys, been trying to get back into the hobby as part of my re-training process. Anyway, working on a MOSFET class a amplifier. Progress is as per the photos. Most of the components soldered, just left the ones supposed to mount onto heatsink. Will mount once I get the casing to mount everything into.

Wanna ask if anyone here knows where to find casing something like in the picture below
