Even power lines can produce a humming sounds.Humming sounds around air conditioner compressor motors, fan motors, well pumps or other motors may be normal if the motor is running, but may also indicate a motor that is unable to start.Dont' rule out medical causes of perceived humming sounds in and around building.

on air conditioners, heat pumps,andmay hum if the motor is having trouble starting. Contactors and relays found on heat pumps and air conditioners and in some furnaces or even hot water boilers may emit a humming noise if the relay is worn, dirty,or damaged.
Humming sounds heard in a building might be traced to any electric motor both in normal operation or particularly at motors that are having trouble starting.Also see.

Gas regulator humming or hissing noises range from probably harmless (some humming sounds at a gas regulator) to very dangerous (hissing of a gas leak).See for details about the sorts of noises found at gas appliance regulators. Humming noises coming from the ground: loud booms, moaning, humming, and other sounds coming from the ground may be due to tectonic plate movement.SeeAlso see - home. Humming and also buzzing noises are also found at low voltage transformers. A low voltage transformer may continue to put out the requried 24-Volts but may keep up a humming noise for months or years. I prefer to replace such devices.Before you blame the electric motor: if you turn off power to an electric motor that you think is the hummer, such as an air conditioner compresor/condenser unit or at a heating furnace, and if you are still hearing humming, find and check the low-voltage transformer. Often an aging transformer will put out an annoying huymming sound. Water pumps, involving an electric motor, are generally rather noisy - a motor noise may shift, however to a more quit hum if the motor is jammed or if the motor is having trouble starting.A.

First off a list of your equipment and possibly a photo of your setup would be helpful.It's a grounding problem.There are a lot of possible explanations.1) You don't have the ground wire attached to your phono pre.2) The ground on the interconnects are not connected properly.3) your interconnects are not shielded and are too close to the motor or power cable.etcFirst off with the volume down unplug the phono cables from the preamp, then turn up the volume. If the hum is still there then the problem is in your preamp.If not the connect the interconnects back and unplug them from the turntable. Then see if the hum is still there if not then the airing in the turntable/cartridge leads are the problem.

Ground connections are where my wires are all connected to, right? You say my tt/arm/cartridge combo is earthed via main plugs and I don't understand that question.Then you mention two core main supply?

I don't understand that either, both the tt and receive have power cables is that what you mean by power supply?I don't understand any of these questions to be honest:(.
