You can see the circuit diagram to make it easier

You can see the image it looks messy, you can easily use perf board but in this video, I'm doing this in an easy way

• First I've connected 22K Resistance to 2 and 4 Pin of TDA2050
• I've connected a 22uf capacitor to the 2nd pin of TDA2050
• 680 Ohms Resistances to the 3rd pin of TDA2050 and the negative pin of the 22uf capacitor
• 3 22K Resistances to pin 1,3 and 5 Pin of TDA2050 and connected all the Resistance together " see the image "
• Negative Pin of 100uf Capacitor to the 3rd pin of TDA2050 and the positive pin to the 3 Resistances
• 2.2 Ohms Resistance to the 4th pin of TDA2050
• 0.47uf capacitor to the 3rd pin of TDA2050 and 2.2 Ohms Resistance " see the image "
• Negative Pin of the 2.2uf capacitor to the 1st pin of TDA2050
• Positive pin of the 1000uf capacitor to the 4th pin of TDA2050

Red and Black wire to 3rd and 5th Pin of TDA2050

• Green wire to Negative of the 1000uf capacitor
• Signal wire to Positive of the 2.2uf capacitor

Input Power

• The black wire is ground and Red wire is Positive

Speaker Output

• Green wire is Speaker Output with Ground

Source Input

• Signal wire is for signal input with Ground

• I used a medium size Heat Shink for Heat Dissipation with a little bit of thermal compound

• I've used a 24V SMPS to power the Amplifier
• And used a bookshelf speaker
