Which is the good schematic attached schematic or datasheet.

I think you will need the following modifications to increase this amps sound performace;
- Ommit the 0.1u, 10K, 10K and 2.2u on NFB circuit..
- Increase the C2 value (47 or 100u-bipolar!) to increase the bass response..
- Add a 680R resistor after C1 in series, to protect amplifiers LTP base..
- Increase C1 value (4u7 MKP, not elko)
And a final word, if you dont have TDA2050 currently then use LM1875 instead of it..

Thank you,

Infact the basic amp I can build now. I am looking for some best sound like WARM, CLEAR TONE, SONIC etc.,

Regards.

@Dxvideo, I was trying to boost bass & treble without adding active/passive crossover.

Then youre on the right way... So keep the feedback components anyway.
However my advices about bass improvement (about C1 and C2 values) are still valid..

I make several amplifiers like this, but with TDA2006 split supply. I added a coil of about 50 microhenry in parallel with 4.7R between IC output and zobel network and speaker to prevent high frequency oscillation in case of long wires to speaker. The set is working fine since 1995 to this date.

Impedance= 4r or more
Power: depends on power supply (Psp > VCC *VCC / RL)
Size: depends on your personal taste.

Good luck.

TDA2050 is a decent powerful chip, it can easily drive 3-8 ohm speakers at 30 Watts average.
