Hey, i soldered the velleman k4001 amp. when a play music though it, it sounds pretty clear and nice, for such a cheap amp. The problem is when i remove the input, the noise is huge!!!
Can someone help me? it should be something with ground, but i have no idea, since when connected to the pc the noise disappears. Maybe because it is grounded with the pc ground??
I need to remove this problem because i want the amp to be mobile, so plugging and unplugging wil happen a lot. And i don't want that noise.
Thank you
