For mr. ROSPA.
2sk1058 transistor too old. It is currently too difficult to buy the original 2sk1058. As for the circuit, there are too many details for such a low-power amplifier you proposed.

the circuit I suggested has a low output impedance and better sound than the original.as for the transistor, this "old"transistor is still produced by RENESAS. moreover, it is freely sold on the Internet.I would advise you to repeat the scheme and not to talk idly about the number of details.
