Hi guys Im just wondering if anyone has any information that might help identify why my amp buzzes. Its not the speakers its the amp itself. As if there is a fan on the inside and there could very well be. If so then I suppose there is no need for alarm but if not then why the buzzing? It works perfectly fine, and always has. It has always buzzed too and was bought as a refurbished amp with a 3 year warranty. So anyone have any suggestions as to what it may be?
