ne5534 compensation
I designed a little headphone amp that has a a 50K volume control, which is connected in between two electrolytic capacitors. When I adjust the volume control I get a crackling noise. It is not the pot. I tried several types. I am using NE5534, and I adjusted the offset bias, and made the gain larger than 3. I rerouted the ground as well.
Anyone got any ideas I have overlooked? I am desperate to get this thing working properly after about 3 weeks of fighting with it hours on end. HELP!!
