In Reply to: RE: Why would reversing AC leads reduce hum in a component? posted by Uncle Mike on February 10, 2017 at 08:04:57:
Back in the 60's before AC plugs had polarizing plugs if a component produced hum the fix was to reverse the plug in the duplex outlet. This was very common for separate amplifiers and pre-amps. Reversing the plug of one of the components would eliminate hum. I don't know why but that's what you did and it worked.
