Hello everyone, I was working on my 386 bass boost project, and I went by the schematic in the datasheet, and it is also attached. It does have good bass, but it also buzzes and acts strangely. Is that just because you need to sacrifice some of the sound quality for better bass? I made a few changes to the schematic, although it follows the same basic principals. The two smaller caps are .047uf because they were more common, and the output cap is 470uf. I started with a 1000uf cap but heard the buzzing, so I changed it to a smaller one but it still didn't go away. Does anyone know what the problem might be? I thought it might be the gain, but I am not sure what I should put across the pins. But when I did experiment with that, something strange happened, the amp was powered on, and I touched my soldering iron to pin one (it also happened with pin 8) and i heard an Asian radio station. It sounded Japanese, but I am not sure exactly what it was. I heard a few others, but the Asian one was the most prominent. Was that just because my soldering iron was acting like an antenna? what happened? Advice would be great. Thank you all.
