hi all,
I made an audio amplifier by my self and came across a problem that I believe one of you can solve it. I am trying to implement the star grounding but when looking at my PCB a place where i could do this is not provided. I it practical to solder the ground wires together or do we have another solution to this that i do not know?

Hi,

I recommend a solid GND plane. No traces, no other signal in this layer.

Star grounding maks the traces to a star point more lenghty. This increases stray inductance.

A GND plane reduces stray inductance and reduces ohmic resistance. And it's easy to design, especially for beginners.
