Welcome!Your kustom with the hum has a problem in the output/driver stage.The hum is DC voltage going to the speakers, which they do not like.Alot of times thats what takes out the speakers when the amp blows. It probibly needs all of 25 dollars worth of parts to get it back up and running. Let us know how it goes.
