Question

I just hooked up my old amplifier to my turntable and started playing some vinyl. I'm getting an incredibly annoying static sound through the headphones I'm listening through, and I'm positive it's not the headphones. The static increases as the volume increases, and is very present. If I turn the amplifier to the FM setting, the static goes away. Any solutions would be INCREDIBLY appreciated. Thanks so much!
