Hello, I decided to rebuild mine 22w amplifier that I burned (had no radiator 😀 so the TDA just fried)

The main pieces you need:

R1 – 39 kΩ
C1, C2 – 10 µF × 25 V (electrolyte)
C3 – 100 µF × 25 V (electrolyte)
C4 – 47 µF × 25 V (electrolyte)
C5 – 0,1 µF × 25 V (ceramic)
C6 – 2200 µF × 25 V (electrolyte)
U1 – Microscheme TDA1554
Input power: 6–18 V.

The blueprints:

Here is the beginning:

I mounted the radiator (not permanently) and the TDA
