i have a kenwood kr-v8060 the humming is in all the speakers, with nothing hooked to it. just playing the radio. I thought that the filter caps in the power supply were causing it. so I changed them out they were 7500uf 71 volt. I put in 10000uf 80 volt but nothing changed. does anyone have any thoughts on this?

thank you kenny
