Hi, my name is Nick. I’m a bass player living in Brooklyn, New York. I am also an electronics hobbyist I’ve mostly built through hole stuff like since modules and guitar effects. I’ve had this dead class D Bass amp lying around for years Finally decided to either try and fix it or get rid of it. So of course, I’m trying to fix it and that’s what I’m doing here and will be posting about it soon. I found out about this forum from a YouTube channel called learn electronics repair.
