I had this old TBA800 IC lying around. So, I designed an audio amplifier circuit. It was fun to solded and works fine. It should support 5W at 16 Ohms load and 24V supply. I only tested it with 12V and 4 Ohms speaker.
The hardest part was soldering the tabs, since they act as heat sink, too.
I used #KiCad for the schematics and layout, although I had to create my own symbol and footprint for the IC. Also had to cut holes for the tabs into the #perfboard.
