So I am using a contactor in an enclosure to switch a load, using 120V (AC) that is coming from an older stereo receiver. When turning on the receiver, power gets sent to the contactor, it engages the coil and switches on the load. The load? A bunch of lava lamps, holiday lights, and other fun things in my man-cave garage.
Problem is, there's a 60 Hz hum it makes. Sometimes it's loud, sometimes medium, sometimes quiet. Turning it off and on will often change it from one to another. I want quiet always. Is there an easy solution for this?
