Can someone answer this for me?When an amplifier is playing I can understand that the current draw (in most instances)will vary depending on how hard it is working. However do these increases in current only get drawn at the supply frequency ie 50 or 60 Hz or are there higher frequency elements to the current being drawn? Hope that makes some sense!
