I've built a 12v Ruby amp and have been playing around with it over the last several weeks. I've noticed at medium to high volume and gain settings that I'm getting some unwanted background noise and was hoping the wise folks here could help me identify the source.
When I strike a chord, it will first ring out clear and then as the chord decays I get this nasty crackling sound in the background along with dying chord. I'm not sure if I'm just overloading the 386 chip and getting some crackly distortion (seems a little odd at only medium gain and volume settings) or if its possibly coming from a bad speaker connection? I'm running the Ruby into a custom 2x8 speaker cab I built. Maybe I need a better speaker cable to connect them with?
Any thoughts would be greatly appreciated. Thanks.
