I changed the 1 uf cap to a slightly larger one, and also oriented it correctly, but the amp started buzzing loudly when power was applied, so i took it off a tried again, yet it still, buzzed. When I disconnected the speaker output wire, it stopped buzzing, so i tried flipping all of the axial caps around, because I thought they might have been reversed, yet still no change. The ground is one big rail of solder, is that a problem? Should they be separated somehow? I have never been taught any of this, so I don't know much about it, this forum is my main source of knowledge, sorry if I am being frustrating.
