That's the wrong way to mount that 2N3055, the die is attached to the bottom of the package where the leads emerge. That's the part of the package that should attach to the heat sink. The top of the package #1 is quite thin and #2 isn't guaranteed to be flat so it plays very little part in hear transfer.
It would be good if you put a resistance of 2.2...3.3 kiloohms between the positive terminal of the input cable and the input capacitor (the one that is placed on the basis of the BD139 transistor). Or if even then the sound distortions would not have been considerably reduced, then a resistance of 4.7 or 5.1 kiloohms would go there. Put the input capacitor on the basis of the BD139 transistor, put in series with it a resistor of the values mentioned above, then put between this resistor and the positive terminal of the input cable another capacitor of the same capacity as that capacitor connected on the basis of the BD139 transistor. This way you could reduce the sound distortions and get a much better sound quality.

Thanks for your feedback
Please mention the wattage and ohms of loudspeaker.
Thanks for your feedback
👍
Nice video. Sir, please make an amp with mosfet K3473 Or any N chanel class A.
We will try...!

Nice projects 🤩💯
Thanks 🔥
Super projects ever 👍❤️
Better than my content 😜
Thanks ❤️
Very pleasant
Ok thanks
Please when you show component value use bigger writing please.
Yes, thanks for the comment
Good👍👍👍💪🙏
Thank you very much
De dónde eres tu
Tremendo

Quiero aprender la electronica
You can
Powerful? at 2 W RMS??? LMAO
Good amp, not powerful. Does not even draw 1 amp at 12.6 volts.
