AC Line Problems


I have big problems regarding AC line noise. I get alot of loud "pops" through my phon stage from appliances in house while listening to phono stage. I had dedicated line installed from the existing panel but to no avail. The house is only wired for 110 amps. Would upgrading to 220 amps help? Any suggestions? How can I determine noise which is coming in from the AC line versus noise which is airborne?

Since all of the noise is collected on your equipment by the ground it must capable of dispensing it. When your house was wired the electrical contractor should have driven a triad of 6-10 grounding rods into the ground and terminated them to the distribution box via 1 ot cable or larger. Depending on the age of you installation (electrical service ) some of the ground connections may have worked loose or corroded. I would suggest installing a new triad ground system and use the proper conductive grease where connections are made. Home Depot should be able to help. good luck
