[QUOTE="Golfather, post: 1087174, member: 414927"] Yes will try moving to another socket, also have a ferrite core around the mains cable as an additional measure but no difference. Is it worth changing the transformer to an external power supply? I swear i could hear a slight hum with the transformer powered but with no connection to board or speaker! Can readily get a 25v 1.5A for a LG soundbar on ebay. [ATTACH type="full" alt="transformer.JPG"]129808[/ATTACH] [/QUOTE]
