I am not so young novice? 😉🙄
Here's a PCB for this amp, but it is not much I like it because there is not transistor for bias (see Figure 1 and PCB) !?😕
cheers

Hi, +1 for the above. And it doesn't have a Baxandall diode, why not ? , rgds, sreten.

Without that its churlish to start worrying about bias issues, it will always be terrible.
