TDA 2050 Amplifier

[audioguru]

The TL072 is old so I would use a newer audio opamp.
The TDA2050 is obsolete and not available anymore (maybe fake Chinese copies are available today?) so I would use a newer audio power amplifier IC.

Is there anything i could do to atleast make it sound good, so it can listenable?

Get rid of the solderless breadboard (use a properly designed pcb instead) and connect the output of the preamp directly to the input of the power amp with short wires (no cable). Then the circuits will not oscillate and will sound fine if you have a volume control turned down to avoid clipping.
